Primary epiploic appendagitis: from A to Z.

Epiploic appendagitis is a rare and uncommon diagnosis that is frequently unknown to clinicians. Inflammation is usually acute and causes abrupt symptoms, but once the diagnosis is accurately made, most patients respond to pain control and conservative management. We report the case of a young woman presenting with acute primary epiploic appendagitis of the right colon. The inflammatory mass was unusually large and occurred a few months after surgery for gastric bypass. This case will give us the opportunity to discuss the clinical presentation of this disease, as well as the potential associations and risk factors and the means for adequate diagnosis and treatment.
