Bailey Andrew D. M.D.; Goldner, Fred M.D.Journal of Clinical Gastroenterology: December 1987 Case Studies: PDF Only Buy Abstract Although the presentation of appendicitis is usually straight-forward, unusual manifestations can delay diagnosis. To emphasize this, we describe a patient who developed progressive sigmoid narrowing with only nonspecific abdominal complaints over a period of months. Eventually, we came upon a pelvic abscess from a ruptured appendix. Clinicians must be ever vigilant for appendicitis and its complications. © Lippincott-Raven Publishers.
