Dr Ansari M A Dept. of Radiology and Imaging Tribhuvan University, Teaching hospital Maharajgunj, Kathmandu,(Nepal).
Primary retroperitoneal teratoma is a rare entity which has a distinctive imaging appearance. To our knowledge, this is the first reported case of teratoma causing diabetes mellitus in a 9-year old boy who was put on insulin. On clinical examination, there was a large tender mass with a well defined margin, caudally in the epigastrium. Ultrasound of abdomen revealed a huge retroperitoneal multiseptated predominantly cystic mass in the upper abdomen. Plain abdominal computed tomography revealed a large well defined cystic mass in the same region. Contrast enhanced abdominal CT revealed a mass with peripheral rim enhancement. It has multiple septa which also enhanced. Clefts containing fat were present adjacent to the septa. Laparotomy with tumour resection was performed. Pathology of the mass disclosed a retroperitoneal cystic teratoma.
