title: Unusual presentation of carcinoid tumor as acute cholecystitis.
abstract: The patient described had signs, symptoms, and laboratory data consistent with acute cholecystitis. A sonogram also suggested cholecystitis, and the gallbladder was not displayed by nuclear imaging. Cholecystectomy revealed the absence of stones but showed carcinoid tumor metastatic to the gallbladder.
