A 69-year-old male presented to the emergency department with left lower quadrant pain, fever, and dysuria for one day. He complained of pneumaturia, but denied any hematuria or fecaluria. On review of systems the patient complained of recent change in the caliber of his stool as well as noted blood in stool. On physical exam the patient had left lower quadrant tenderness, no palpable masses, and bowel sounds were present.
The patient had a past medical history of hypertension and diverticulosis, and a past surgical history of hernia repair with no complications. CT of the abdomen and pelvis were performed with intravenous contrast and oral contrast to look for any fistula or abscess formation.
