Retroperitoneal cystic lymphangioma is a rare benign tumor. Most patients eventually experience some symptoms that necessitate therapeutic intervention. Excision is the treatment of choice, and some cases of laparoscopic resection have been reported. We report another case of a huge retroperitoneal cystic lymphangioma that was successfully excised laparoscopically with the SAND balloon catheter. Large cystic lymphangioma was downsized by puncturing and aspirated with the SAND balloon catheter. Laparoscopic surgical technique should be considered for treatment of selected cystic lesions of retroperitoneal origin.
