An inflamed necrotic appendix epiploicum with immediate contact to a non-inflamed appendix vermiformis: a case report

Epiploic appendagitis is a rare cause of focal abdominal pain which, depending on its localisation, can mimic a variety of abdominal diseases. We describe a patient with an inflamed necrotic appendix epiploicum with immediate contact to a non-inflamed appendix vermiformis mimicking acute appendicitis. Considering the rare localization, this is the first report of this kind in the literature.

We present the case of a 50-year-old Caucasian man who presented with classic signs of acute appendicitis. On clinical exam, McBurney and Blumberg signs were positive. Additionally he had fever, leucocytosis (12/nl) and a slight increase in C-reactive protein (1 mg/dl). Based on the clinical presentation, the patient was taken to the operating room to perform an appendicectomy. Surprisingly, we found an inflamed necrotic appendix epiploicum, located immediately on a non-inflamed appendix vermiformis, which was ligated and excised.

This case report demonstrates that epiploic appendagitis can mimic acute appendicitis on clinical exam and should be considered in the broad spectrum of abdominal disease presenting with right lower quadrant pain.
