Cavernous hemangioma of the scrotum: a case report

A 19-year-old male consulted our department, complaining of a painful scrotal mass. On palpation, the mass was discriminated from testis, epididymis, and spermatic cord in the left scrotum. He underwent total excision of the mass. Pathologic examination revealed cavernous hemangioma. Scrotal hemangioma is a relatively rare lesion and this is the 37th case reported in Japan.     

Venous hemangioma of the mediastinum: apropos of a case

A case of mediastinal venous hemangioma is reported. It's a benign tumor rarely found in the mediastinum. In the last six years, we only know three cases reported and none of them in our country. Clinical manifestations were cough and pleuritic pain. The diagnosis was suggested by radiologic examination and was confirmed by histologic study after thoracotomy. The mass was totally removed surgically and the evolution of the patient was favorable.     

A case of racemose hemangioma of the right bronchial artery and intercostal to pulmonary arterial anastomosis]

We reported a case of racemose hemangioma of the bronchial artery and intercostal to pulmonary arterial anastomosis. A 67-year-old woman was admitted because of repeated hemoptysis. Bronchoscopic examination revealed a torous lesion of the right B7 bronchus. Intercostal angiography demonstrated communications between right dilated, meandered intercostal arteries and right pulmonary artery. Bronchial angiography showed dilatation and convolution of the right bronchial artery. Angiographic embolization of the right bronchial artery and the right intercostal artery was underwent. There was no recurrence of hemoptysis one year after the embolization procedure. We think that angiographic embolization is an effective method of treatment of hemoptysis due to racemose hemangioma of the bronchial artery and intercostal to pulmonary arterial anastomosis.     

Spontaneous rupture of splenic hemangioma: a case report

Splenic hemangioma is rare. The major problem concerning splenic hemangioma is the difficulty of preoperative diagnosis. No characteristic signs allow the specific diagnosis of this tumor. Spontaneous rupture is the main complication, occurring in up to 25% of cases reported. In cases of rupture of the tumor, splenectomy is a life-saving and mandatory procedure. A case of spontaneous rupture of splenic cavernous hemangioma is presented and the literature is reviewed.     

A case of left ventricular hemangioma

Left ventricle hemangioma in a 54-year-old man is reported. He was admitted to our hospital for chest discomfort. Coronary angiograms showed normal coronary arteries and a contrast blush in the left interventricle septum. Transesophageal echocardiogram also demonstrated the small floating tumor in the ventricular septum below the right coronary cusp. With the aid of cardiopulmonary bypass, the tumor was resected completely through transaortic approach. Histological examination revealed capillary hemangioma. The patient had uneventful recovery. To our knowledge, this is the seventh case of a left ventricular hemangioma treated surgically reported in the world literature.     

Hemobilia caused by a giant benign hemangioma of the liver: report of a case

We report herein the extremely unusual case of a 39-year-old woman in whom a giant cavernous hemangioma caused hemobilia. Cavernous hemangioma is the most common benign neoplasm of the liver and rarely causes any clinical symptoms or signs, while hemobilia usually occurs secondary to accidental operative or iatrogenic trauma, vascular disease, inflammatory disorders, gallstones, or tumors of the liver. Although invasive or malignant hepatic tumors often result in a communication between the biliary tract and the blood vessels, only one case of hemobilia caused by a benign cavernous hemangioma has ever been reported, but with no details about the patient. Our patient presented to a local hospital with severe melena as the initial main symptom, where ligation of the right hepatic artery was performed. This failed to relieve her symptoms, and she was subsequently referred to our department where a right hepatectomy was performed. Histopathological examination revealed no malignancy combined with the tumor; however, the hemangioma was exposed to the bile duct in segment VIII, which was presumably the cause of the hemobilia. This patient remains in good health almost 6 years after her operation. To the best of our knowledge this is the first case report of hemobilia caused by a cavernous hemangioma, and is accompanied by a detailed analysis.     

The pulmonary air meniscus sign in a case of sclerosing hemangioma

A 57-year-old woman was admitted to our hospital because of a slowly growing pulmonary tumor with a 34 year history. Chest roentgenogram on admission showed a 42 mm sharply demarcated solitary tumor in the left upper lobe. Chest CT revealed a slit-like pulmonary air meniscus. Left upper lobectomy was performed. A specimen from the resected lung histologically showed solid, papillary and hemorrhagic patterns, and the diagnosis of pulmonary sclerosing hemangioma was therefore made. Pulmonary air meniscus sign in pulmonary sclerosing hemangioma is rare. We think one possible mechanism in the production of an air meniscus sign in sclerosing hemangioma is bleeding in communication with a bronchus.     

Cardiac cavernous hemangioma mimicking pericardial cyst: atypical echocardiographic appearance of a rare cardiac tumor

Cavernous hemangioma is a rare tumor with infrequent cardiac involvement. Preoperative or antemortem diagnosis may be difficult. Several prior case reports have described echocardiographic findings of cavernous hemangioma. We report here a 50-year-old white female patient with this tumor. Transesophageal echocardiography detected a mass with an echocardiographic appearance not previously described for cavernous hemangioma. The tumor appeared as a large echolucent unilocular cystic mass, leading to an erroneous preoperative diagnosis of pericardial cyst. This previously unreported finding should be recognized by echocardiographers in the evaluation of cardiac masses.     

Double-chamber right ventricle: a case report

The double-chamber right ventricle is a congenital cardiac malformation usually associated with other cardiac defects, seldom isolated and in adult subject. It is characterized by the presence of an anomalous bundle that divides the right ventricle into two chambers. The clinical and electrocardiographic signs of isolated double-chamber right ventricle are few and not specific. An echocardiographic diagnosis of isolated double-chamber right ventricle is reported. In a 18-year-old asymptomatic male with systolic murmur 2/6 at third space over the left sternal border, right ventricular hypertrophy and intraventricular conduction delay at ECG, two-dimensional echo showed an anomalous transversal muscle bundle that divided the right ventricle into two chambers, superior and inferior. Color Doppler showed a diastolic tricuspidal-like flow through a paraseptal discontinuity of the bundle and a systolic jet that reached the right atrium, with a pressure gradient of 30.9 mmHg. The absence of symptoms and other cardiopathy, without significant right outflow tract obstruction, was considered as an index of a good prognosis; therefore cardiac catheterization was not advised.     

Surface-based hemangioma of bone: three case studies and a review of the literature

The islet organ of the Atlantic hagfish, a cyclostome, phylogenetically is the most original islet parenchyma. It is well equipped with blood vessels, but lacks nerves. The aim of the present study was to evaluate the relative proportions between regional blood flows in these animals with a microsphere technique and with laser-Doppler flowmetry. As regards the results obtained in the kidneys, gills, and islet organ, the data were essentially the same found using both methods. Approximately 20% of the injected microspheres were found in the kidneys; when corrected for weight, the gill bodies and the islet organ were also found to have the same blood perfusion. The blood flow to the brain and that of the gut and the liver were only approximately 30% and 10%, respectively, of that to the kidney. Topical application of the nitric oxide donor, sodium nitroprusside failed to affect the islet blood flow. Apart from this observation, this non-innervated "primitive" islet parenchyma did not differ from that of the amply innervated mammalian islets with regard to their high basal blood perfusion.     

Hemifacial spasm caused by a hemangioma at the geniculate ganglion: case report

OBJECTIVE AND IMPORTANCE: Hemifacial spasm is rarely caused by facial nerve lesions in the temporal bone. Intratemporal facial nerve hemangiomas may initially present as facial spasm. CLINICAL PRESENTATION: A 30-year-old woman developed right hemifacial spasm. Physicians observed slight weakness on the right side of her face, in addition to the hemifacial spasm, but routine radiological examinations did not detect any abnormal findings along the course of the facial nerve. Although the patient underwent neurovascular decompression, the spasm persisted postoperatively. Two years after surgery, the right facial palsy progressed. Concurrently, the hemifacial spasm diminished. High-resolution computed tomography demonstrated a small mass lesion expanding the cortex of the right petrosal bone involving the geniculate ganglion of the facial nerve. INTERVENTION: The patient underwent a second craniotomy through a subtemporal extradural route, and the tumor was completely removed. A pathological examination demonstrated a cavernous hemangioma. CONCLUSION: Routine radiological examinations may fail to detect small intratemporal facial nerve hemangiomas, particularly at the geniculate ganglion. Therefore, when physicians encounter atypical facial spasm, the intratemporal portion of the facial nerve should be carefully examined using high-resolution computed tomography.     

Intraparenchymatous vascular tumors of the testicle: report of a new case of cavernous hemangioma

The occurrence of a vascular tumour at the intraparenchymatous testicular level is a fact little reported in the literature. Searching for such events, 19 cases were found all of which showed benign clinical behaviour. The most commonly seen histological pattern is cavernous haemangioma (11 patients). Mean age at presentation is 19 years old and the most usual pre-operative diagnosis, germinal cell neoplasia. Since there are no specific ultrasound patterns that may allow to differentiate benign from malignant masses, inguinal orchiectomy is the choice treatment in this type of lesions. Furthermore, the case of a 44-year old patient with hypoechogenic solid mass in left testis who consulted for sporadic episodes of long-standing scrotal pain is presented. After radical exeresis of the gonad, the histological analysis showed existence of testicular cavernous haemangioma.     

Blunt rupture of the right hemi-diaphragm with complete dislocation of the right hepatic lobe: report of a case

We present herein a case of blunt rupture of the right hemidiaphragm occurring with complete intrathoracic dislocation of the right hepatic lobe in a polytraumatized patient. The initial chest X-ray was interpreted as right-sided hemothorax, and a thoracic drainage tube was accidentally placed into the liver. A computed tomography scan subsequently revealed diaphragmantic rupture with intrathoracic liver dislocation. It was possible to reposition the liver, and the extended dorsal diaphragmatic rupture was closed primarily through an abdominal approach. The problems associated with the diagnosis and operative treatment of fresh right-sided blunt traumatic diaphragmatic ruptures are discussed following this case report.     

Bilateral horizontal gaze palsy with pontine cavernous hemangioma: a case report

Epilepsy is a common condition. In most cases, treatment with medications is satisfactory. When antiepileptic drugs fail to control the seizures, further evaluation may be warranted. EEG-video monitoring can allow a definitive diagnosis of epileptic seizures to be made by differentiating epileptic events from paroxysmal symptoms that can be mistaken for seizures (i.e., pseudoseizures). In addition, it usually allows one to accurately diagnose the seizure type, facilitating selection of the best possible treatment. Occasionally, surgery may be a therapeutic option in patients with intractable seizures.
