Aggressive angiomyxoma is a rare benign tumor, arising in the pelvis usually presenting clinically as a perineal soft tissue mass displacing normal pelvic structures. The tumor is characterized by its locally aggressive nature and its tendency to recur after surgical resection. Although descriptions of this tumor have recently appeared in the pathology literature, to date, the radiological appearance of aggressive angiomyxoma has not been well documented. The CT scan in the following case report demonstrates the extent and location of the tumor, as well as its tendency to displace, rather than invade adjacent structures. These findings are consistent with the pathological characteristics of aggressive angiomyxoma, and therefore, can assist in its preoperative diagnosis.
