Abstract

A 49-year-old woman was admitted to our hospital due to macroscopic hematuria. Contrast-enhanced computed tomography revealed left hydronephrosis, a tumor at her left ureter, pseudoaneurysm and ovarian cystoma. Prior to the operation, the tumorous lesion was considered as left ureteral cancer without metastasis (cT4N0M0; stage IV). Left nephroureterectomy was performed. After the surgery, pathological examination revealed that this lesion was extrinsic endometriosis originating from the ureter.We here report this case of ureteral endometriosis that presented with atypical clinical findings along with a review of the literature.
