MRI features of a perineal mass pathologically proved as a leiomyoma
The patient had at the same time a laparoscopic cholecystectomy for chronic calcular cholecystitis as mentioned on the pathological report.
Perineal leiomyomas are extremely rare benign mesenchymal tumors, usually of superficial location1. The differential diagnosis includes a wide variety of soft tissue tumors such as sarcoma 1. The mobility of the mass and the absence of extension to the adjacent tissues are more in favor of benign origin 1.
