Abstract
BACKGROUND: Extrapelvic endometriosis may occur at unusual sites. We report a rare case of an endometrioma presenting as a suburethral mass in a woman without a previous surgical history. CASE: A 27-year-old, nulliparous woman presented with a painful suburethral mass, dyspareunia and voiding difficulty. Ultrasonographic examination showed an echolucent mass over the suburethral area measuring 3.7 cm in diameter. Double-balloon cystourethrography showed that the mass did not communicate with the urethral lumen. Complete excision was performed later. The final pathologic examination revealed endometriosis. CONCLUSION: Extrapelvic endometriosis should be considered as a possible diagnosis for a suburethral mass even if no pelvic endometriosis is detected from a detailed history and vaginal examination. Ultrasonography and double-balloon cystourethrography may be helpful for clinical evaluation. Complete excision is advisable for management of a suburethral endometrioma.
