Case report
A 52-year-old man presented with symptoms of left renal colic. These were accompanied by long-standing constipation, perineal pressure, and a slow urinary stream and hesitancy. His past medical history included childhood bladder schistosomiasis, which resolved with medical management at the age of 12.
The physical findings consisted of a large, rubbery-like mass, situated anterior to the rectum. It displaced the prostate laterally and was intimately related to the left seminal vesicle.

Two thirds of schwannomas have

In fact, there is only one prior report of a pelvic schwannoma occurring in a male patient [1]. Furthermore, the occurrence of a presacral schwannoma after prior pelvic surgery has never been previously described.
