Teratoma, Abdominal sonography
Because of variant structures of the teratomas, the sonographic features have many varieties reported in literatures. We report here a case of mature retroperitoneal teratoma which held three different components in a tumor, a solid part and two cysts. In one of the cysts, the sonographic features showed a special appearance resembling "fire-works" which have not been reported before. This finding may be helpful for the diagnosis of teratoma.
