Acute urinary retention caused by endometrial carcinoma with large cystic cervix

Several pelvic masses have been known to cause urinary retention due to a mass effect with the bladder being obstructed secondary to compression of the urethra or bladder neck.

We report the extremely rare case of endometrial carcinoma with an enlarged cystic cervix which resulted in acute urinary retention. A 92-year-old woman was referred for acute urinary retention. Vaginal ultrasound revealed a 70 × 70 × 65 cm-sized cystic lesion in the cervix. Voiding became normal immediately after the incision and drainage of the mass. Ultrasound performed after the incision revealed a hyperechogenic mass with a honeycomb appearance in the uterine cavity. Endometrial biopsy revealed well-differentiated adenocarcinoma of the endometrium. Total hysterectomy and bilateral salpingo-oophorectomy was performed.

The possible existence of endometrial carcinoma should be considered when the enlargement of cervix is clinically suspected in an elderly woman even if there is no vaginal discharge or bleeding.
