Abstract
A case of lymphangioma of the lesser omentum is reported.
A 55-year-old man was admitted to our hospital because of abdominal distention. Laboratory data showed nothing in particular. Ultrasonography and computed tomography showed a multilocular cystic tumor situated among the liver, the stomach and the pancreas. The tumor was connected with a structure, which was probably the lesser omentum. The tumor was soft and its shape was altered with change in position. X-ray of the stomach, ERCP and angiography revealed only the findings of compression and magnetic resonance imaging showed low intensity area in T-1 and high intensity area in T-2. Under a diagnosis of lymphangioma of the lesser omentum, laparotomy was performed. The tumor was surrounded by the lesser omentum and connected with the lesser curvature of the stomach, but was not connected with the liver and the pancreas. The tumor was 8×7×5 cm in size and a multilocular cyst. Histologically, the diagnosis of lymphagioma was established.
Lymphagmoma of the lesser omentum is very rare and 14 cases seen in the Japanese literature were reviewed.
