Leiomyoma of the urinary bladder - A rare differential diagnosis

One case of a thirty-one year old female with a leiomyoma of the urinary bl adder is presented. The intravesical tumor measured 3 x 4 x 5 cm and grew w ithout causing any clinical symptoms. The urologists performed various radi ologic procedures and cystoscopy. Under the diagnosis of uterine fibroid th e patient was referred to the gynaecologist for subsequent surgery. Vaginal ultrasound already questioned previous diagnosis. Laparotomy revealed a tu mor originating from the bladder. The tumor was enucleated from the bladder wall after advertent opening of the bladder. The patient received transien t prophylactic bilateral ureteral stents and recovered quickly without intr a- or postoperative complications. Leiomyoma of the urinary bladder is a ra re entity but still should be considered for differential diagnosis as a tu mor of nonuterine origin.
