Endometriosis in Bladder Diverticula

We report a case of endometriosis of the bladder diverticulum that was created after cesarean section.

Case Report:

A 45-year-old woman was diagnosed with abdominal pain during menstruation and hematuria after cesarean section.
Pelvic tests and pelvic ultrasonography are normal in non-menstrual days. However, the last pelvic ultrasound showed a solid 9 × 6 mm anterior mass that adheres to the posterior wall of the bladder during menstruation.
During a menstrual period, a cystoscope showed a 1-centimeter bulging nodular mass in a posterior wall diverticulum. Histologic diagnosis of endometriosis was in the bladder diverticulum wall.

The post-operative period was not a problem and the clinical symptoms were completely resolved after removing the endometriosis of the bladder diverticulum
