A retroperitoneal angiosarcoma is rare. Especially, a cystic change in retroperitoneal angiosarcoma is extremely rare and it is difficult to distinguish an angisarcoma with a cystic change in the differential diagnosis with other retroperitoneal cystic masses. We report here a case of a cystic change in a retroperitoneal angiosarcoma of a 61-year-old woman who complained of abdominal pain. Imaging studies, including ultrasonography and computed tomography, detected a lobulating cystic mass with inner enhancing irregular septations and walls in the retroperitoneum. The tumor was surgically resected and was histopathologically diagnosed as an angiosarcoma.
