Cholelithiasis Demonstrated on Hepatobiliary Scintigraphy as a Photopenic Defect Within the Inferior Portion of the Liver

Abstract

A 47–year–old man presented with the clinical findings of acute cholecystitis. During hepatobiliary scintigraphy using Tc–99m DISIDA, a persistent photopenic defect was noted within the inferior portion of the liver in the region of the gallbladder. Abdominal ultrasonography revealed large gallstones with acoustic shadowing within a normal–sized gallbladder. Eleven large gallstones were found within a normal–sized intrahepatic gallbladder at surgery.
