Omental and mesenteric lipomas are very rare benign lesions of mature adipose tissue. They are well-defined, noninvasive, and encapsulated masses that can be discovered in asymptomatic patients or may cause variable nonspecific symptoms depending on their size and location. The omental and mesenteric lipoma has confusing features in ultrasound; however, computed tomography and magnetic resonanc...

Primary omental infarction (POI) has a low incidence worldwide, with most cases occurring in adults. This condition is rarely considered in the differential diagnosis of acute abdominal pain in childhood. Herein, we present a case of omental infarction in an obese 10-year-old boy who presented with acute abdominal pain in the right lower abdomen. The ultrasound (US) examination did not reveal t...

Omental infarction is an uncommon but important cause of acute abdominal pain, which frequently mimics other surgical presentations. The current series describes five cases of idiopathic omental torsion and infarction and provides a review of the literature. We discuss the diagnosis of primary omental infarction as well as the role of conservative and surgical management.

Lipolytic and lipoprotein lipase (LPL) activities were studied in isolated human adipocytes obtained from two intraabdominal depots (round ligament and omental) and from the subcutaneous abdominal region of nine severely obese premenopausal women (with body mass indices ranging from 37 to 51 kg/m2), aged 36 +/- 3 yr, undergoing gastrointestinal surgery. Both fat cell weight and LPL activity wer...

Omental pregnancy is a very rare form of ectopic pregnancy. Here we presented a case of primary omental pregnancy diagnosed at surgical exploration. A 28 year old woman submitted with severe abdominal pain, without any delay of menstruation. History of the patient revealed no use of contraceptive method. There was no gestational sac in the endometrial cavity and no tubal ring in the adnexa, but...

Omental tumors are most commonly found in the pediatric population, with hemangiomas being one of rarest types. These can occur any organ, a higher prevalence skin and subcutaneous tissue. Although they extremely rare, omental tumors, including hemangiomas, often involve greater omentum. We present case 70-year-old male patient that presented to our hospital abdominal pain, distension, inabilit...

INTRODUCTION Omental infarction is a rare and often misdiagnosed clinical event with unspecific symptoms. It affects predominantly young and middle aged women. CASE PRESENTATION This is a case report of a 26-year-old Caucasian woman with spontaneous omental infarction two weeks after normal vaginal delivery. CONCLUSION Omental infarction is a differential diagnosis in the postpartum acute a...

Studies comparing adipose tissue metabolism in central versus peripheral fat depots have generated equivocal data. We examined whether regional differences in abdominal subcutaneous and omental adipose tissue metabolism in women exist and whether they persist across the spectrum of body fatness and abdominal adiposity values. We measured adipocyte size; lipoprotein lipase (LPL) activity; and ba...

INTRODUCTION PGF2α may be involved in the regulation of adipose tissue function. OBJECTIVES 1) To examine PGF2α release by primary preadipocytes, mature adipocytes and whole tissue explants from the subcutaneous and omental fat compartments; 2) To assess which PGF synthase is the most relevant in human adipose tissue. METHODS Fat samples were obtained by surgery in women. PGF2α release by p...
