EPIDIDYMAL LEIOMYOMA - SONOGRAPHIC FEATURES

The epididymal leiomyoma is a benign neoplasm that usually appears as a slow growing, painless scrotal mass.(1-4) Although the leiomyoma is the second most common neoplasm of the epididymis, detection frequentl y leads to radical orchiectomy on the mistaken presumption of malignan cy To date, sonographic characterization of these masses has been limi ted.(5-7) Because the scrotal leiomyoma shares histologic features wit h the more familiar uterine leiomyoma, it is perhaps not surprising th at these two tumors should also share common sonographic features. We describe the ultrasonographic characteristics of an epididymal leiomyo ma that exhibited multiple recurrent sharp shadows that did not origin ate from calcifications. To our knowledge, this pattern, common in lei omyomas originating from the uterus,(8) has not been recognized previo usly in leiomyomas in the scrotum.
