Cystic lymphangioma of the lesser sac (omental bursa)

摘要

Cystic lymphangioma is a benign, slow-growing tumour that usually occurs in children and the most frequent location is the head and neck. Intra-abdominal cystic lymphangiomas are rare. We present herein a case of cystic lymphangioma of the lesser sac (omental bursa) in a 58-year-old woman. The patient presented with nonspecific abdominal symptoms. Abdominal ultrasound and computerized tomography revealed a cyst within the lesser sac. Laparotomy was performed and the tumor was removed completely and intact. Histologic examination showed cavernous lymphangioma. The postoperative course was uneventful and the patient was discharged on the 5th postoperative day. During a 1-year follow-up there was no radiologic sign of recurrence. Introduction Cystic lymphangioma is a benign, slow-growing tumour derived from the lymphatic vessels. It usually occurs in children and the most frequent location is the head and neck, while Intra-abdominal location is an extremely rare entity 1 . We report a case of cystic lymphangioma of the lesser sac (omental bursa) in a 58-year-old woman. Case Report A 58-year-old woman presented with a 6-month history of mild epigastric pain, aggravated immediately after food intake, early satiation and anorexia. A 6kg weight loss during this period was also mentioned. In physical examination, mild epigastric tenderness was noted with no other physical signs. Abdominal ultrasound revealed a multiseptated elliptic cyst anterior to the pancreas, measuring 125x130mm. An abdominal contrast-enhanced computed tomogram showed a multilocular elliptic cyst measuring 12.5x10x15cm within the lesser sac. Displacement of the stomach anteriorly and external compression of the corpus of the pancreas was obvious.
