INTERMITTENT OBSTRUCTIVE JAUNDICE DUE TO A DUODENAL DIVERTICULUM: LEMMEL’S SYNDROME INITIALLY MISSED ON CT BUT LATER EVINCED WITH MAGNETIC RESONANCE CHOLANGIOGRAPHY AND ENDOSCOPY

ue to a mechanical obstruction of the common bile duct, Lemmel's syndrome arises when a duodenal diverticulum induces obstructive jaundice. Intermittent obstructive jaundice is a rare conditionreported in 2-7% of patients undergoing studies. Although the majority of the diverticula are asymptomatic when the symptoms are present, they usually consist of jaundice, abdominal pain, or acute cholangitis; these symptoms can be intermittent. The imaging methods in diagnosing Lemmel's syndrome are crucial; the CT scan and magnetic resonance cholangiography (MRC) revealed periampullary diverticula on the medial wall of the second portion of the duodenum. Treatment varies depending on the aetiology and underlying cause. However, diverticulectomy remains the standard of care.
