Abstract
A 75-year-old man presented to a neighboring hospital because of abdominal pain was referred to our hospital with a diagnosis of intestinal obstruction. Abdominal CT scan showed a multilocular giant cyst in the abdominal cavity which had compressed the intraabdominal organs toward the right, at where part of the small intestine had swollen. Intestinal obstruction due to the giant cystic tumor was diagnosed and the patient was operated on. The tumor was present at the retroperitoneum and had replaced the intestine ventrally. As the tumor involved the left kidney, combined resection of the left kidney was performed. The resected specimen involved a 30 × 28 cm multilocular cystic tumor. The histopathological diagnosis was lymphangioma. It is believed that many retroperitoneal lymphangiomas grow slowly, but there are some lymphangiomas which show a relatively rapid growth like in this case. Careful selection of therapeutic methods would be mandatory.
