A 62-year-old man had right upper quadrant abdominal pain, jaundice, fever, and leukocytosis. Tc-99m HIDA imaging showed nonvisualization of the gallbladder and increased pericholecystic hepatic uptake. The latter scintigraphic finding, known as a 'rim sign,' is often associated with acute gangrenous cholecystitis. Surgery in this patient showed acute cholecystitis with focal areas of gangrenous necrosis associated with a solitary calculus.
