Abstract

Spontaneous bladder perforation is a rare presenting feature of bladder malignancy. We describe an unusual case of a patient, admitted to emergency, with diffuse abdominal pain due to spontaneous bladder rupture in association with a micropapillary carcinoma. A diagnosis of an intraperitoneal bladder perforation was made during an emergency operation. Aspects of etiology, clinical presentation, diagnosis and management are described. Although cases of spontaneous carcinomatous bladder rupture are associated with high morbidity and mortality, prompt identification and treatment can lead to favourable outcomes.

A computed tomography scan of the bladder shows reduced bladder capacity with bladder muscle thickening, the most pronounced in the area of the vault, no clear sign of tumour recurrence, enlarged benign prostatic hyperplasia, and also without lymph node metastases in the pelvic cavity.
