Gastric duplication cyst in an adult

Gastric duplication cysts are rare in adults and usually asymptomatic. In most cases they are discovered incidentally by abdominal ultrasound, CT, or upper gastrointestinal x-rays. Most of the duplications (82%) are cystic and do not communicate with the stomach. Approximately half of the cases are associated with other congenital anomalies. We report a 59-year-old woman operated on for a pancreatic mass that proved to be a gastric duplication cyst. The cyst was resected and the postoperative course was uneventful.     

Relapsing pancreatitis due to juxta-pancreatic duodenal duplication cyst with pancreatic ductal communication

BACKGROUND: Various animal studies and ecologic studies suggest an inverse association between low dietary selenium intake and risk of various types of cancer. PURPOSE: The goal of this prospective cohort study was to investigate the association between toenail selenium levels and risks of stomach cancer and colorectal cancer. METHODS: Our cohort study on diet and cancer started in The Netherlands in 1986 with enrollment of 120,852 subjects aged 55-69 years. Of this number, 58,279 were men and 62,573 were women. Following the case-cohort approach for analysis of the data, we randomly selected from the cohort a subcohort of 3500 subjects (1688 men and 1812 women). After 3.3 years of follow-up, 155 incident cases of microscopically confirmed stomach cancer, 313 cases of colon cancer, and 166 cases of rectal cancer had been detected in the cohort. Toenail selenium data were available for 104 patients with stomach cancer, 234 with colon cancer, and 113 with rectal cancer and for 2459 subjects from the subcohort. RESULTS: In a multivariate analysis, the relative rates (RRs) of stomach cancer for subjects in increasing quintiles of toenail selenium level were 1.00, 0.44, 0.59, 0.84, and 0.64 (trend, P = .491). For men, there was some evidence for an inverse association between toenail selenium levels and stomach cancer: The RR for those in the highest compared with the lowest quintile of toenail selenium was 0.40 (95% confidence interval = 0.17-0.96), but the trend was not statistically significant (P = .136). For stomach cancer in women, there was no negative association with toenail selenium levels. Toenail selenium level was not associated with the risk of colon or rectal cancer. After exclusion of cases diagnosed in the 1st year of follow-up, the RRs of colon cancer for increasing quintiles of toenail selenium were 1.00, 1.27, 1.17, 0.75, and 1.07 (trend, P = .544); for rectal cancer, RR estimates were 1.00, 1.73, 0.83, 1.58, and 1.12 (trend, P = .890). CONCLUSIONS: These data support a suggestive but inconsistent inverse association between selenium levels and risk of stomach cancer. Our findings, like those of other studies, do not suggest an inverse association with risk of colorectal cancer.     

Posterior communicating artery aneurysm presenting with haemorrhage into an arachnoid cyst

A patient is reported on with a subarachnoid haemorrhage (SAH) from an aneurysm of the posterior communicating artery, who initially presented with a sentinel bleed into an arachnoid cyst and normal magnetic resonance angiography (MRA) of the intracranial vasculature which led to a delay in diagnosis. Although this is a very rare presentation of a relatively common condition, it is important to recognise the importance of intracystic haemorrhage in such circumstances as well as the limitations of MRA, as a delay in diagnosis may have serious clinical consequences.     

Thyroglossal duct cyst with papillary carcinoma in an 11-year-old girl

A case of primary papillary carcinoma arising in a thyroglossal duct cyst is reported in a young girl. This is a rare finding, with only five pediatric cases in the total of 115 cases reported in the literature. Subsequent management is described, including the role of scintigraphy and radioiodine ablation.     

Dacryocystitis associated with nasolacrimal duct cyst

An infant presented with persistent epiphora after successful probing of the lacrimal system. Examination of the nose showed a cystic structure occluding lower portion of the lacrimal drainage system. In cases of recurrent obstruction, nasal examination and endoscopic marsupialization may help guide the clinician towards the most appropriate treatment.     

Occipital encephalocele associated with mediastinal enteric duplication cyst

We report a new case of tracheobronchopathia osteoplastica revealed by bronchopulmonary infections. The review of the literature enables us to summarize the clinical, endoscopic, morphological features, as well as pathogenic hypotheses.     

Pulmonary sequestration associated with a gastric duplication cyst

A case of right subdiaphragmatic extralobar pulmonary sequestration (PS) associated with a gastric duplication cyst is reported. To the authors' knowledge such a case has not been reported previously in the English literature. PS was first noted as a defect on a nuclear liver image. The duplication cyst was defined by ultrasonography. A review of the English literature is included.     

Thyroglossal duct cyst causing airway obstruction in an adult

Thyroglossal duct cysts, though not uncommon, rarely present with evidence of laryngeal compromise. The case presented is one of the very few cases with documented laryngeal invasion reported in the English language. Of clinical significance is the patient's presentation with laryngeal symptoms of choking and dysphonia in the presence of a small anterior cervical mass. While the thyroglossal duct cyst usually presents as an asymptomatic anterior neck mass, this case illustrates the importance of considering a thyroglossal duct cyst in any patient with airway compromise in the absence of a neck mass.     

Incomplete urethral duplication with cyst formation in a dog

Incomplete urethral duplication with cyst formation was diagnosed in a dog that had soft, fluctuant, subcutaneous swellings in the ventral perineal and penile areas and a history of nocturia and incontinence during recumbency that were unresponsive to treatment with antibiotics. Retrograde urethrocystography, voiding urethrography, double-contrast cystography, radiography after direct administration of contrast medium into cystic structures, and excretory urography were performed to evaluate the urinary tract. Communication between the cysts and the urethra was demonstrated radiographically only after intralesional injection of contrast medium. Nocturia and incontinence resolved after surgical removal of the urethral duplication and cysts. The dog was clinically normal 1 year after surgery.     

Aneurysm of the anterior communicating artery associated with accessory middle cerebral artery--case report

A 63-year-old female presented with an anterior cerebral artery aneurysm associated with accessory middle cerebral artery. The aneurysm was located on one of the duplicate anterior communicating arteries, and the accessory middle cerebral artery originated from the anterior cerebral artery adjacent to this aneurysm. The recurrent artery of Heubner was not recognized. The accessory middle cerebral artery may have been involved in the genesis of the aneurysm by changing the hemodynamics in the anterior cerebral arteries.     

Melanosis peritonei associated with enteric duplication cyst. A case report

Melanosis peritonei is extremely rare, and only five cases have been reported in the English literature, four in association with ovarian dermoid cysts, and one with a peritoneal cyst. We describe an additional case occurring in a girl two years of age who also had an enteric cyst. This is the first reported case of melanosis peritonei not associated with an ovarian teratoma, but with an enteric duplication cyst. Melanophages were present focally in the submucosa, superficial muscle layer, and ulcer bases of the cyst and extensively as small nodules on the peritoneal surface and in the omentum. The tendency of perivascular nodular aggregation of melanophages favors a hematogenous (or lymphatic) spread rather than implantation. Although clear evidence of melanocytic aggregation is lacking, are speculate that the melanin originated from the esophageal-like squamous mucosa of the cyst.     

Cystic duplication of ejaculatory duct: case report

A case of complex malformation of the genito-urinary tract, including cystic dilatation and partial duplication of the ejaculatory duct is reported. The lesion was visible on retrograde and anterograde vasovesiculography; its complete removal was possible using an abdominal approach.     

Papillary adenocarcinoma of a thyroglossal duct cyst

Carcinoma in thyroglossal duct tissue is a rare occurrence. A case of papillary adenocarcinoma in a thyroglossal duct cyst is presented. Local excision by the Sistrunk technic appears adequate for the noninfiltrating, nonmetastatic lesion. Thyroid hormone should be given as a suppressive agent. Continuous follow-up is necessary for the rest of the patient's life.     

Bisalbuminemia disclosing primary hyperparathyroidism with fistulized pancreatic false cyst

Discovery on a protein electrophoregram of a bisalbuminemia can orientate according to its migration fast or slow to an hereditary mutation of an amino acid, or an acquired form by excess of beta lactamines due to renal insufficiency or by the rupture of a pancreatic pseudocyst in the peritoneum. This is this late mechanism that we report in this case of bisalbuminemia related to an opened pancreatic pseudocyst secondary to an adenoma of the parathyroid gland.
