Extraperitoneal Rupture of a Bladder Diverticulum and the Role of Multidetector Computed Tomography Cystography

Abstract

Nontraumatic rupture of the bladder is less widely recognized than traumatic rupture, with a challenging early diagnosis due to high variability in clinical presentations. We report a case of extraperitoneal rupture of a bladder diverticulum in a patient with diabetes mellitus who presented with paralytic ileus. Despite conservative management, the patient developed sepsis requiring surgical treatment. Urinary tract infection and bladder outlet obstruction were considered to be potential mechanisms of the rupture. Multidetector computed tomography cystography should be used as the first-line modality when evaluating for a suspected bladder rupture, even in patients with nontraumatic bladder rupture.
