This case involves a woman who presented to the hospital after experiencing persistent lower abdominal pain. The emergency physician suspected appendicitis and ordered a CT. The report showed thickening of the appendix and accumulation of fluid in the peritoneal cavity. Although the differential on the CT report included a ruptured appendix, the general surgeon diagnosed the woman with diverticulosis and began antibiotic treatment. While the woman was in the hospital, her appendix ruptured and she developed sepsis, prompting a long recovery. An expert in general surgery was requested to review the records and opine on whether the surgeon missed the diagnosis of a ruptured appendix that sepsis in this patient.
