[A case of myelolipoma originating from bilateral adrenal glands; a comparison of CT and pathological findings].

We experienced a case of bilateral retroperitoneal tumor incidentally on CT which was carried out on suspicion of either cholelithiasis or choledocholithiasis. In company with other radiologic studies, US, angiography etc. we were able to make a correct diagnosis of adrenal myelolipoma preoperatively. Among these studies, CT coincided well with the structure of pathological findings and is thus the most powerful method for the diagnosis of myelolipoma. The case was discussed in addition to the studies of other literatures.
