omental torsion is caused by the rotation of the greater omentum on its axis which may lead to tissue infarction and necrosis. it is a rare cause of acute abdomen. signs, symptoms and paraclinical data are not specific. the patients usually undergo laparotomy for acute abdomen of poorly defined origin. high index of suspicious is required for the diagnosis of this entity. the diagnosis is usual...

The omentum, a rich source for trophic and angiogenic factors, was explored as a potential intermediate transplant site to facilitate long-term survival of chromaffin tissue. Autologous rat adrenal medullas were grafted into omental pockets. All grafts became densely vascularized. The grafted chromaffin tissue exhibited strong immunoreactivities for tyrosine hydroxylase, synaptophysin and chrom...

Idiopathic segmental infarction of the greater omentum is an uncommon cause of acute abdomen. The etiology is still unclear and the symptoms mimic acute appendicitis. Its presentation simultaneously with acute appendicitis is still more infrequent. We present a case of a 47-year old woman without significant previous medical history, admitted with an acute abdomen, in which the clinical diagnos...

Germ cell tumors predominantly involve the gonads but may rarely be found outside of the gonads, primarily in midline structures. We describe the case of a 27-year-old male with an asymptomatic 8 cm teratoma located within the lesser sac of his omentum. This is the fourth case of a teratoma located within the lesser sac of the omentum, which provides the opportunity to make some comparisons. Fi...

Inguinal hernia continues to be the most common hernia. In majority of cases the swelling goes undetected thereby allowing it to assume a bigger size. Huge inguinoscrotal hernias which are traditionally described as giant inguinoscrotal hernias are still encountered in day to day general surgical practice. The contents usually vary from omentum to a significant portion of either the small bowel...

small meals (owing to distortion of the stomach and cardio-oesophageal junction); and (5) an abdominal fluid thrill but no shifting dullness, indicating a localised collection of fluid and clotted blood. The likely pathogenesis of the haemorrhage is over-distension of the stomach with tearing of a small blood vessel in the lesser omentum. The blood tracks inferiorly, stripping peritoneum from t...

BACKGROUND Hemangiopericytoma occurs with increasing frequency in 5th decade of life and has prediction for retroperitoneum and extremities. A case of a local recurrence and metastases of hemangiopericytoma is described. CASE PRESENTATION Recurrence of hemangiopericytoma in the greater omentum and the jejunal mesentery as well as metastases in the retroperitoneal space were diagnosed in a 61-...
