Cholelithiasis demonstrated on hepatobiliary scintigraphy as a photopenic defect within the inferior portion of the liver.
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.
