Abdominal Distension due to Large Omental Cyst

Omental and mesenteric cysts are both rare entities, mostly found in children. Incidence rate in adults is between 1/100,000-1/250,000. Upon clinical examination they usually display symptoms of abdominal distension, with or without a palpable mass. Reported cases in the literature usually display symptoms of abdominal distension, abdominal pain, and painless mass, or possible ascites [1]. Differentiation from ascites or tuberculosis should be done. Treatment for this condition is complete surgical resection. We describe the clinical presentation of a 58 y.o man with abdominal distension for the last six months. The computer tomograph (CT) scan revealed an intra-abdominal mass 15,0x14,0 cm, with well differentiated borders. Histopathological diagnosis was confirmed as lymphangioma of the omentum.
