Abstract
A 74-year-old female with severe obesity and uncontroled diabetes mellitus presented with right lower abdominal pain. Cecal diverticulitis was diagnosed with by abdominal computed tomography (CT) scan. We started conservative therapy with antibiotics, but 3 days later, the abdominal pain became worse. The CT scan showed thickening of the wall of the cecal and ascending colon. The necessity of an operation was considered, but severe complications were anticipated and a wide range of intestinal resection would probably have been required. Percutaneous drainage appeared to be possible if a pericecal abscess had occurred, because the pain was localized, so we continued with more conservative therapy. Three days later, a pericecal abscess was detected which was drained via a percutaneous puncture. The patient improved and was discharged from hospital after control of her diabetes mellitus.
