A 70-year-old woman with appetite loss and vomiting was found in ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) to have a unilocular cystic tumor surrounded by the left liver lobe, stomach, and pancreas. Under a diagnosis of cyst of the lesser omentum or mesenterium, we conducted a laparotomy. The cystic tumor was located in the lesser omentum alone and not connected to other organs. Histopathological diagnosis showed lymphangioma. A lesser omental cyst is relatively rare, and even rarer in the aged.

Key words
lesser omental cyst, lymphangioma
