Abstract
A rare case of bladder diverticulitis with symptoms of peritonitis is reported. The patient was an 84-year old man who began to exhibit a fever around December 10, 2001, the patient received treatment for an urinary tract infection at a local hospital. He began to experience abdominal pain on December 13 and was referred to our hospital. A physical examination performed at the time of admission identified muscular defense and the Blumberg sign in the lower central abdomen. A contrast-enhanced CT scan of the abdomen showed a well-defined ventriculus extending from the bladder, leading to a diagnosis of peritonitis resulting from a bladder puncture; emergency surgery was performed on the same day. A diagnosis of bladder diverticulitis was made during the surgery, and a resection of the vesical diverticulum and a partial resection of the bladder were performed. The postoperative course was uneventful, and the patient was discharged on Day 28. Although bladder diverticulitis is a common condition, bladder diverticulitis combined with symptoms of peritonitis is rare and worth reporting.
