Lemmel syndrome is a rare clinical condition characterized by cholestatic jaundice caused by compression of the common bile duct (CBD) by a periampullary duodenal diverticulum. The authors present a patient with post-cholecystectomy jaundice, in whom 99m Tc-Mebrofenin hepatobiliary scintigraphy showed pooling of tracer activity in the proximal CBD with delayed bilioenteric drainage. Single photon emission computed tomography/computed tomography detected a duodenal diverticulum medially displacing and compressing the distal CBD, which was corroborated by magnetic resonance cholangiopancreatography.
