@entity8 @entity5409 @entity1494 @entity3041 @entity3833 @entity490 @entity73362
A 19-year-old male was admitted with left lower @entity490 and @entity3833 . Excretory urograms showed only a right kidney. V.C.G. showed a @entity5409 over the bladder. Computerized tomography revealed a huge retroperitoneal cystic mass located near the bladder. It seemed to be a huge @entity1494 , but the diagnosis was not clearly confirmed before operation. Through a lower abdominal midline incision, the cystic mass structure was removed. The specimen was a @entity8 with non-functioning @entity3041 . The removed mass was 91 @entity73362 78 mm in size, and 120 g in weight. The intrarenal fluid was 350 ml. A brief discussion and review are made. To our knowledge, only 3 such case have been described in the Japanese literature.
