Epiploic appendagitis of the vermiform appendix––An unusual mimic of acute appendicitis

摘要

Epiploic appendagitis is a condition resulting from ischemia or necrosis involving the appendage epiploica either due to torsion or spontaneous thrombosis of the venous outflow. It is one of the myriad causes of acute abdominal pain and can masquerade clinically as appendicitis, omental infarction, sclerosing mesenteritis and even diverticulitis. Epiploic appendagitis of the vermiform appendix is a rare entity, clinically indistinguishable from appendicitis. We present a 45-year-old male patient with 4-day duration of right iliac fossa pain and tenderness, with strong clinical suspicion of acute appendicitis. CT scan of the abdomen and pelvis demonstrated Epiploic appendagitis of the vermiform appendix, whilst the appendix remained uninflamed. The patient was thus discharged with conservative management without having to go undergo needless surgery, thereby avoiding the potential complications thereof.
