title: The complementary role of hepatobiliary scintigraphy and abdominal sonography in a patient with a hepatic cyst and suspected acute cholecystitis.
abstract: A 51-year-old woman was admitted with suspected acute cholecystitis. A large hepatic cyst was found incidentally by abdominal sonography, which displaced an "abnormal" gallbladder. Hepatobiliary scintigraphy visualized the gallbladder and excluded acute cholecystitis, but required the anatomic information from sonography to verify the abnormal location of the gallbladder. Additionally, scintigraphy showed the cyst not to communicate with the biliary tract. Pathologic findings revealed mild chronic cholecystitis and a simple mesothelial hepatic cyst. This case illustrates the complementary role of hepatobiliary scintigraphy and abdominal sonography in patients with distorted hepatobiliary anatomy and suspected acute cholecystitis.
