The subject of mesenteric cyst is one of considerable interest to all embryologists and abdominal surgeons, and the specimen that was removed in this case was one of those rare forms that have a cyst wall more than suggestive of the wall of part of the alimentary canal. At present the belief is2 that excepting hydatids and cysts

We report on an optimized method for the in vitro culture of tissue cyst-forming Neospora caninum bradyzoites in Vero cells and the separation of viable parasites from host cells. Treatment of tachyzoite-infected Vero cell cultures with 17 microM sodium nitroprusside for 8 days severely scaled down parasite proliferation, led to reduced expression of tachyzoite surface antigens, and induced the...

Introduction Hydatid cyst is a parasitic disease caused by Echinococci. The most commonly affected organ is liver, followed by lungs. Hydatid disease of the chest wall is extremely rare. The aim of this study is to report a case of chest wall Hydatid cyst with literature review. A 20-year-old pregnant lady presented with left hypochondrial and lower chest painful swelling. There was 10 × 15 cen...

A young lady presented to the emergency department with pain in the abdomen for 1 day. She had a history of similar pain in the past. Her clinical examination was unremarkable, except for mild abdominal tenderness. Further investigations suggested diagnoses of acute pancreatitis and a duodenal cyst. Magnetic resonance cholangiopancreatography (MRCP) revealed a cystic lesion in the duodenum in c...

A 58-year-old man who had been undergoing treatment for chronic pericarditis for 15 months was found to have a calcified mediastinal mass shadow on a chest X-ray and was referred to us for further study and treatment. Chest computed tomography and magnetic resonance imaging showed an anterior mediastinal multilocular tumor with rim calcification. Tumor markers were within normal limits. The pat...

Pericardial cysts are reported by some authors, but epicardial cysts are extremely rare. We report one case of epicardial cyst that was detected incidentally and was removed successfully. Furthermore, unusually, pathological examinations confirmed that the cyst wall was looked like a vessel wall.

In addition to the liver, human hydatidosis has been reported in the lung, brain, abdominal viscera, muscles, and heart chambers. Infarction of the brain has also been documented. Arterial embolism of the lower extremities by hydatid cyst, however, is extremely rare. In the presented case, acute ischemia of the patient's left leg led to gangrene and amputation. Complete workup for localizat...

OBJECTIVE To describe the computed tomography (CT) features of neuroendocrine tumors (NETs) and solid pseudopapillary tumors (SPTs) with unilocular cyst-like appearance, and to compare them with those of unilocular cystic tumors of the pancreas. MATERIALS AND METHODS This retrospective study was approved by our Institutional Review Board, and informed consent was waived. We included 112 pancr...

Ultrastructural changes during encystation of Polysphondylium palltdum, a cellular slime mould, include an increase in fibnllar material in the cytoplasmic matrix, the formation of cytoplasms microprojections at the cell periphery and the occurrence of tiny vesicles and some larger vacuoles near the cell periphery. The cyst wall appears first as a fluffy, loose network of fibrils. In the mature...

A 63-year-old man who underwent insertion of a lumboperitoneal shunt developed gait disturbance. He had undergone surgery for gastric cancer 7 years and for ileus 5 years previously. Head computed tomography (CT) revealed enlargement of the ventricles. Abdominal CT revealed a cyst in the abdominal region and the distal segment of the peritoneal shunt tube located within the cyst. Laparotomy rev...
