Spontaneous bladder diverticulum rupture due to a squamous cell carcinoma of the bladder: a case report.

While bladder rupture is most of the time secondary to external injury such as trauma or iatrogenic events, spontaneous bladder rupture (SBR) is a rare condition which is mostly associated with bladder cancer, neurologic bladder or radiotherapy. We report a case of a 63-year-old patient with an invasive squamous cell bladder carcinoma who presented acute peritonitis caused by a SBR while being prepared for radical surgery. CT-scan helped to confirm diagnosis and emergency cystectomy was performed. SBR should be considered in differential diagnosis of peritonitis. On time diagnosis and adequate surgery could improve its prognosis.
