Laparoscopic excision of a retroperitoneal cystic lymphangioma encasing the renal vessels

A 55-year-old woman, with a retroperitoneal cystic mass, incidentally found during evaluation for the cause of right upper quadrant pain, was referred to our hospital from a local clinic. Computed tomography, performed at our hospital, revealed a multilobulated cystic lesion in the right perinephric space, encasing the renal vessels, suggestive of a cystic lymphangioma. A cystic abdominal lymphangioma is a rare tumor in adults, which is difficult to diagnose preoperatively. Surgical excision is known as the treatment of choice; however, only three cases of laparoscopic excision have been reported. We report a case of a successful laparoscopic excision of a retroperitoneal cystic lymphangioma encasing the renal vessels of the renal hilum.
