Giant leiomyoma of the urinary bladder: A case report

Urinary bladder leiomyoma is a rare tumour accounting for less than 0.5% of all urinary bladder tumours. Till now, less than 250 cases were documented with variable sizes, most of them were less than 10 cm in maximum diameter. Here we present a 68- year-old female patient with urinary bladder giant leiomyoma measuring about 13 cm. She presented with right loin pain. Postcontrast computed tomography of the abdomen and pelvis revealed a large posterolateral right-sided urinary bladder mass with moderate right hydroureteronephrosis. It was managed by partial cystectomy. The patient had an uneventful postoperative course. Postoperative pathological examination of the specimen confirmed giant leiomyoma of the urinary bladder.
