A Case of a Retroperitoneal Cystic Lymphangioma Treated by Percutaneous Catheter Drainage and Sclerotherapy

(CT) scan showed a large, lobulated, septated, retroperitoneal cystic mass (10×9.5×5 cm) in the left anterior pararenal space with intracystic hemorrhage surrounding the inferior mesenteric vein (IMV). Because of the high operative risk, we performed a tubogram of the cystic mass, percutaneous catheter drainage (PCD), and ethanol sclerotherapy. The follow-up abdominal CT scan showed that the cystic mass had decreased in size. He is well without relapse of the retroperitoneal cystic mass for 13 months after discharge. Sclerotherapy with PCD should be considered as initial therapy for patients with retroperitoneal cystic lymphangiomas at high surgical risk. (Korean J Pediatr Gastroenterol Nutr 2010; 13: 86∼91)
