Suburethral endometrioma. A case report.
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.


METHODS
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.


CONCLUSIONS
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.
