Jejunal diverticulitis: an unusual cause of an intra-abdominal abscess - coronal Computed Tomography reconstruction can aid the diagnosis

Jejunal diverticulitis is a rare condition that can present with an acute abdomen and be referred for imaging. We present the case of an elderly patient who at CT was diagnosed with an intra-abdominal abscess involving both jejunum and transverse colon. However, the underlying eitiology was not initially clear until small bowel barium follow-through. Pertinent points regarding CT findings in jejunal diverticulitis are discussed, and practical recommendations in small bowel diverticulum recognition and diagnosis are made.
