Simulating binocular visual field status in glaucoma

A 73-year-old male was admitted to our hospital because of productive cough and infiltrate on the chest roentogenogram. The underlying diseases was found to be multiple myeloma. He received a physical examination in June, 1996. The chest X-ray and CT scan on admission showed an infiltrative shadow with multiple bulla in the left upper lung field. Internal use of antibiotics and drip infusion of IPM/CS were ineffective. The chest X-ray showed air-fluid level in left upper peripheral bullous lesion and a percutaneus needle aspiration of the lung was performed. The specimen was pus with blood and microscopical examination of smears revealed no acid-fast bacilli, but Mycobacterium szulgai was isolated and identified by DNA-DNA hybridization method. The patient was treated with isoniazid and rifampicin, and improved in a few months. There are a few case reports of pulmonary infection due to M. szulgai associated with emphysematous bulla of the lung in Japan. M. szulgai infection of the lung is similar to M. kansasii infection in respect to clinical features (improvement of chest abnormal shadow, efficacy of drug).     

A case of mediastinal seminoma undergoing extremely cystic degeneration

A-25-year-old male had an abnormal shadow on chest X-ray. CT and MRI films revealed a cystic lesion, with irregular nodules in the right anterior mediastinum. A cystic teratoma was suggested. Antero-axillary thoracotomy revealed a cystic lesion originating from the right lobe of the thymus. The lesion was extirpated, along with the right lobe of the thymus. The cystic part of the lesion, filled with brown fluid, was occupied by several masses originating from the wall of the tumor. Pathologically, the lesion was diagnosed as a seminoma undergoing cystic degeneration. The patient was given post-operative irradiation of 20Gy. No apparent recurrence has been detected 33 months after surgery. Mediastinal seminomas generally occur as a solid tumor consisting of stroma and tumor cells. However, this case report suggests that mediastinal seminomas may undergo extremely cystic degeneration.     

Atypical mycobacteriosis (Mycobacterium xenopi) with "initial aggravation"

A 66-year-old man was admitted to Nara Medical University Hospital because of sputum production and fevre. A chest X-ray film obtained on admission revealed many cysts and an infiltrative shadow in the right upper lung field. The patient was treated with antimycobacterial drugs (isoniazid 400 mg, streptomycin 0.75 g, and rifampicin 450 mg) because acid-fast bacilli were detected in his sputum. Although the symptoms and laboratory data improved, a new infiltrative shadow developed in the right lower lung field two months after the start of treatment. Transbronchial biopsy specimens showed intraluminal organizing exudate and alveolitis. The new lesion resolved when treated with the same antimycobacterial drugs. Mycobacterium xenopi was cultured from the sputum 80 days later. This is the third reported case of atypical mycobacteriosis (non-tuberculous mycobacteriosis) due to M. xenopi in Japan with the "initial aggravation" seen in some patients with typical pulmonary tuberculosis.     

A case of lung and liver cystic hydatid disease in a 31-year old man

The case of cystic hydatid disease in a man working in the past in Greece was described. He was admitted to hospital because of a very marked limited shadow in the right lung. During diagnostic procedures, two cysts were revealed in the liver. Punction of lung lesion was not performed. He was operated on with a suspicion of hydatid disease. Diagnosis was supported with a parasitologic examination.     

A case of huge abscess extended from anterior neck to left lung and lateral chest wall

62-year-old woman admitted our hospital with pain of left upper extremity from the left chest and dysphasia. Chest X-ray showed the huge mass shadow in the left lung field. Diabetes mellitus and inflammatory reaction such as high fervor, leukocytosis, CRP and ESR accentuation were recognized. Conservative therapy was done at first, but mass shadow on X-ray increased, and swelling appeared from the neck to the left lateral chest wall. And the same site appeared like subcutaneous emphysema. Computed Tomography showed mass shadow which was enlarged and spread in lung parenchyma and left chest wall with bubble image. Incision and open drainage was performed for the left chest wall but origin bacteria was detected in neither anaerobic nor aerobic culture of pus. Inflammation and mass shadow of left upper lung field have decreased gradually. The patient discharged without bronchoalveolar fistula. Abscess extending from the neck or chest wall with diabetes mellitus is very rare.     

Percutaneous drainage in the treatment of emphysematous pyelonephritis: 10-year experience

PURPOSE: We investigated the effect of percutaneous drainage for the treatment of emphysematous pyelonephritis. MATERIALS AND METHODS: A retrospective analysis was done of 25 patients with emphysematous pyelonephritis who were treated initially with computerized tomography (CT) guided percutaneous drainage during a 10-year period. The patients were concomitantly treated with antibiotics, fluids, and correcting blood glucose and/or ureteral obstruction. We also compared our results of percutaneous drainage to CT findings. RESULTS: CT identified 12 patients with emphysematous pyelonephritis who had gas with little fluid and 13 who had gas with renal or perirenal fluid collections. In 20 of 25 patients (80%) antibiotic therapy combined with percutaneous drainage constituted the only treatment required. Three patients (12%) whose clinical status improved after percutaneous drainage subsequently underwent elective nephrectomy without further complications. Two patients (8%) died of multiple organ failure. There was no correlation between the gas patterns of emphysematous pyelonephritis and initial success with the antibiotics and percutaneous drainage. There were no recurrences and no complications during a followup of 1 to 10 years (mean 5). Mean duration of treatment was 5.54 weeks (range 1 to 12.6). CONCLUSIONS: CT is an efficient imaging method for diagnosis, guiding the drainage procedures and monitoring response to percutaneous drainage of emphysematous pyelonephritis. Antibiotic therapy combined with CT guided percutaneous drainage of emphysematous pyelonephritis is an acceptable alternative to antibiotic therapy with surgical intervention.     

Transient inhibition of L929 cell mitosis and locomotion by argon ion laser irradiation

A 48-year-old woman was admitted to our hospital because of abnormal shadow on the chest X-ray. Chest contrast CT scan showed roundly mass in the posterior mediastinum which were combined with and without contrast elements, and chest MRI (T2 weighted) showed high signal intensity. These features suggested mediastinal cyst or extralobar sequestration. The operation was performed through left 6th intercostal thoracotomy. Two different lesions connected to the mediastinum were confirmed, a cystic tumor and small accessory lung. The former was diagnosed as bronchogenic cyst and the latter as extralobar pulmonary sequestration.     

A patient with allergic bronchopulmonary candidiasis showing a high serum level of soluble interleukin 2 receptors

An 84-year-old man was admitted to Yonezawa City Hospital with fever, cough, hemoptysis and progressive dyspnea. He had complained of wheezing asthmatoid and exertional dyspnea for the previous 10 years, regardless of the season. On admission, chest radiographs revealed a diffuse ground-glass shadow, fibrotic change, and volume reduction. Arterial blood gas analysis showed extreme hypoxemia. A computed tomographic (CT) scan of the chest showed not only faint ground-glass opacities and dense patches in the whole lung field, but also central bronchiectasis. Laboratory tests revealed that both total serum levels of IgE and specific IgE for Candida albicans were elevated. In the bronchoalveolar lavage fluid, lymphocyte, neutrophil and eosinophil percentages were high, and the CD4/CD8 ratio was low. We diagnosed the fibrotic stage of allergic bronchopulmonary candidiasis. During treatment with hydrocortisone and fluconazole, eosinophilia in the peripheral blood was observed, and serum candida antigen was positive. In addition, high serum levels of soluble interleukin 2 receptors were observed in this patient.     

A case of chronic necrotizing pulmonary aspergillosis successfully treated with combination therapy of antifungal drugs and ulinastatin

A 64-year-old woman with a history of old tuberculosis, had a fungus ball shadow with meniscus sign in the upper right lung field on a chest X-ray film in 1991. Based on the chest X-ray findings, pulmonary aspergilloma was suspected. Because the size of the intracavitary fungus ball increased, the patient was treated with itraconazole over one year in 1995, but there was no improvement. One month later, she was admitted because of fever, hemoptysis and productive cough, and chest X-ray showed an enlargement of intracavitary mass and infiltrative shadow in the right lung. Chronic necrotizing aspergillosis was diagnosed on the basis of her clinical and radiographic features, and positive serological test. Although itraconazol and amphotericin B were given, cavity and intracavitary fungus ball shadow kept growing. Combination therapy of antifungal drugs and ulinastatin markedly improved symptoms and resulted in complete disappearance of the fungus ball on chest CT scan.     

Percutaneous catheter drainage of tension pneumatocele, secondarily infected pneumatocele, and lung abscess in children

OBJECTIVE: To describe the use of percutaneous catheter drainage of tension pneumatocele, secondarily infected pneumatocele, and lung abscess in children. DESIGN: Retrospective case series. SETTING: A 24-bed pediatric intensive care unit. PATIENTS: Patients with tension pneumatocele, secondarily infected pneumatocele, or lung abscess. Tension pneumatocele was defined as an expanding intraparenchymal cyst compressing adjacent areas of the lung. Infected pneumatocele and lung abscess were defined, respectively, as intraparenchymal thin-walled cyst or thick-walled cavity containing an air-fluid level and purulent fluid. INTERVENTIONS: Seven pneumatoceles/lung abscesses were percutaneously drained in five patients. After computed tomography of the chest was obtained to localize the optimum site for drainage, a modified Seldinger technique was used to insert an 8.5-Fr soft catheter percutaneously into the cyst/cavity. The catheter was left in place until drainage (fluid and air) stopped. MEASUREMENTS AND MAIN RESULTS: All patients had clinical and radiologic improvement and were afebrile within 24 hrs after drainage. Bacterial culture grew aerobic bacteria from three cysts/cavities, anaerobic bacteria from one, and mixed bacteria from three. One patient had three secondarily infected pneumatoceles. Four of five secondarily infected pneumatoceles were under tension in two patients receiving mechanical ventilation. In both patients, the trachea was extubated within 24 hrs of drainage after prolonged mechanical ventilation. The number of days the catheter was in place ranged from 1 to 20 days. CONCLUSIONS: Percutaneous catheter drainage of tension pneumatocele, secondarily infected pneumatocele, and lung abscess can be performed safely and effectively in children. Early drainage is helpful, both as a diagnostic and therapeutic procedure. Drainage of tension pneumatocele may assist in weaning from mechanical ventilation. Computed tomography of the chest is helpful in determining the optimum site for percutaneous drainage.     

Treatments for hepatocellular carcinoma in cirrhosis : practical aspects]

A 44-year-old woman was admitted to our hospital for evaluation of an abnormal lung shadow. Chest computed tomography (CT) revealed a tumor surrounded by air-space and an infiltrative shadow in the right S2. Right upper lobectomy was performed and pulmonary sclerosing hemangioma was diagnosed. Usually, pulmonary sclerosing hemangioma shows a solitary round nodule on a chest CT scan. We report a case of pulmonary sclerosing hemangioma with an unusual shadow on a chest CT scan, and review the literature.     

A case of spontaneous remission of paragonimiasis miyazakii

A 52-year-old man was admitted with fever and chest pain. Chest X-ray showed a soft infiltration in the right lung and bilateral pleural effusions. A strong tuberculin reaction was elicited. Significant laboratory findings included eosinophilia (37% in peripheral blood and 78% in pleural fluid) and elevated IgE levels (577 IU/ml in sera and 6700 IU/ml in pleural fluid). Adenosine deaminase activity in the pleural fluid was high. No helminth eggs were detected after repeated examination of the pleural fluid and sputum. No definitive diagnosis was made. Three months of chemotherapy with INH and rifampicin resulted in little improvement. Corticosteroid was then administered orally under a tentative diagnosis of idiopathic eosinophilic pleurisy, which proved to be a successful treatment and resulted in a marked reduction of pleural fluid volume. Two years after discharge, the patient's chest X-ray was normal and laboratory findings were normal including the eosinophil count and IgE level. The pleural fluid obtained at the first admission and kept frozen was subjected to immunological analysis for anti-parasite antibody activity. The pleural fluid showed an unexpectedly high titer of antibody activity (x6400 dilution) against Paragonimus miyazakii antigen assayed by double diffusion Ouchterlony method. Examination of the sera obtained from the patient two years after discharge, however, revealed no detectable antibody activity against the parasite antigens assayed either by Ouchterlony or ELISA method. We concluded from the clinical as well as laboratory findings that the patient had recovered from Paragonimiasis miyazakii without specific intervention for the disease.     

Successful treatment of a giant bulla by thoracoscopic excision and laser ablation

A 39-year-old male complaining of shortness of breath on mild exertion. Radiographs revealed that a giant bulla occupied more than half the area of the right lung field. Thoracoscopic excision of the giant bulla was performed using some autosutures. After the emphysematous lesion was consolidated by laser ablation, it was sutured using PDS thread. The bulla in the left lung was similarly excised 3 weeks after the first procedure. The FEV1.0% improved from 72% to 89% after excision and laser ablation of a giant bulla and bullae. Thoracoscopic excision and laser ablation of a giant bulla appears to be an effective alternative to conventional thoracotomy.     

Management of the clinically positive neck in organ preservation for advanced head and neck cancer

An 82-year-old man was treated with isoniazid (INH) because of a low-grade fever. On the 9th day of treatment, dry coughing and general malaise developed. On the 30th day, he was admitted to our hospital. A chest-X ray film showed infiltrative shadows in the right middle and lower lung fields, but a chest CT scan showed an abnormal lung density in the right lower lobe. Abnormal laboratory findings included leucocytosis, liver dysfunction, hypoxemia, low vital capacity, low diffusing capacity and a high level of C-reactive protein. A differential cell count of the bronchoalveolar lavage fluid (BALF) showed many neutrophils and lymphocytes; examination of a specimen obtained by transbronchial lung biopsy (TBLB) revealed edema of alveolar walls, lymphocyte infiltration, and proliferation of type II alveolar epithelial cells. A drug lymphocyte stimulation test (DLST) against INH was positive. After discontinuation of INH, symptoms resolved, laboratory findings became normal, and the infiltrative shadows in the right middle and lower lung fields disappeared. The clinical course and the findings of BALF, TBLB, and DLST suggested the diagnosis of pneumonitis caused by INH.     

A case of chronic lung abscess showing a cloudy shadow of the right upper lobe, diagnosed by transbronchial aspiration cytology

A 58-year-old healthy woman was admitted to our hospital on 8th October, 1991 for detailed investigation of an abnormal shadow on chest roentgenogram, which was detected by mass survey. The chest roentgenogram showed a cloudy shadow of the right upper lobe, and retrospectively, this abnormal shadow had been present since 1986. Flexible fiberoptic bronchoscopy showed complete obstruction of right B1b bronchus by regenerated bronchial mucosa. Aseptic pus was detected in the obstructed bronchus by means of transbronchial aspiration cytology (TBAC) and chronic lung abscess was diagnosed. The chest roentgenograms of this case is very unusual, and we were unable to find a similar case of chronic lung abscess diagnosed by means of TBAC.     

A case of epididymal sarcoidosis

We reported a case of epididymal sarcoidosis. The patient was a 13-year-old boy with a chief complaint of right scrotal mass. On physical examination, a firm, nontender 7 mm mass was palpable in the right hemiscrotum and appeared to involve the head of the epididymis. Ultrasonography showed a highly echogenic mass in the epididymis. A routine chest X-ray revealed lymphadenopathy of the mediastinum and reticular shadows in bilateral lung fields. Because the lesion might be confined to the epididymis, a partial epididymectomy was performed. The histopathologic specimen showed noncaseating granulomas consistent with sarcoidosis. Lung biopsies also revealed noncaseating granulomas. Subsequent pulmonary function studies revealed a mild obstructing ventiratory defect, therefore therapy was instituted with systemic steroids. There were no further recurrent scrotal masses. Although sarcoidosis is known to affect many organs, involvement of the genital system is relatively rare. Most of the patients with intrascrotal sarcoid lesions have an abnormal chest X-ray. We need to differentiate these lesions from advanced testicular cancer. This is the 5th case of intrascrotal sarcoidosis in Japanese literature.     

Tonoko pneumoconiosis with deposition of titanium

A 56-year-old man had worked as a furniture painter and had been exposed to tonoko polishing powder for 30 years. He had complained of dyspnea on exertion for 7 years, and was admitted to our hospital in 1991. A chest X-ray film revealed large opacities and emphysematous changes in both lung fields. Tonoko pneumoconiosis was diagnosed after transbronchial lung biopsy. Home oxygen therapy was given because of progressive hypoxemia, but the patient died of respiratory failure. At autopsy, examination of the lungs showed severe emphysematous changes, and collapse of alveoli. Many gray masses resembling coating cement were seen especially in the upper lobes. Microscopical examination showed that the large opacities were composed of hyaline nodules, similar to silicotic nodules, with anthracosis. Scanning electron microscopy with X-ray microanalysis revealed a high concentration of titanium in the gray mass. A low dose of titanium would not be expected to induce fibrotic changes in the lung, but a high dose and long-term exposure might have that effect. Titanium contained in paint might have exacerbated tonoko pneumoconiosis in this patient.     

A case of spontaneous hemopneumothorax occurred after thoracic drainage

A 21-year-old man; complaining of left chest pain and dyspnea, was admitted to our hospital with a diagnosis of spontaneous pneumothorax. Though chest X-ray on admission did not show hemothorax, chest drainage revealed intrapleural bleeding. As chest X-ray on the following day showed evident fluid level, emergency operation was carried out with a diagnosis of spontaneous hemopneumothorax. Bleeding point was a ruptured vessel between parietal pleura and bulla in apex of lung. The bulla was resected following hemostasis. After improvement of complicating postoperative re-expansive pulmonary edema, the patient was discharged on the 18th postoperative day. On treatment of spontaneous hemopneumothorax, existence of such a case as ours should be taken into account.     

A case of sarcoidosis associated with chronic eosinophilic pneumonia

A 38-year-old man was hospitalized in our university hospital because of pulmonary opacities with bilateral hilar and mediastinal lymphadenopathy seen on chest radiograph. Eosinophilia was observed in the circulation and bronchoalveolar lavage (BAL) fluid. Histological examination revealed noncaseating epithelioid granulomas and eosinophilic infiltration in the lung. Based on these findings, a diagnosis of sarcoidosis combined with chronic eosinophilic pneumonia was made. The infiltrates on chest radiograph and BAL eosinophilia were promptly reduced with corticosteroid therapy, but only mild reduction was observed in diffuse nodular shadows and hilar and mediastinal lymphadenopathy, and high amounts of lymphocytes in BAL fluid remained. Increased IFN-gamma, IL-4 and IL-5 were detected in the BAL fluid, and corticosteroid therapy reduced IL-4 and IL-5 (Th-2 cytokines) but not IFN-gamma (Th-1 cytokine). These cytokine levels in BAL fluid were intimately correlated with the clinical course of sarcoidosis and chronic eosinophilic pneumonia.     

Imported pulmonary coccidiodomycosis apropos of an anatomo-clinical study

The case is reported of a 41-year-old Arizona woman who, during a European tour, consulted a Lausanne (Switzerland) physician to whom she reported poor general health and, in particular, localized pains in the right thorax. Although the clinical condition appeared normal, radiology of the thorax revealed a round, hollow shadow in the right lung. Since tuberculosis seemed the most likely diagnosis, the patient underwent antibacillary treatment. Three months later the lesion appeared to have increased in volume, and exploratory thoracotomy was performed with removal of the inferior lobe of the right lung. In the pulmonary parenchyma three greyish, well-defined nodules were found. Exhaustive research disclosed the fungal nature of these lesions through the demonstration of parasitic elements typical of Coccidioides immitis.
