Abstract
We reviewed various imaging approaches in 22 patients with gallbladder cancer. Nineteen had had ultrasonography and nine computed tomography performed. A gallbladder mass or diffuse wall thickening was seen by ultrasonography in 42% and computed tomography in 33% of patients. A significant number of patients had no gallbladder wall abnormality detected by ultrasonography (37%) or computed tomography (56%). Performing both ultrasonography and computed tomography improved the diagnostic rate; in this subgroup the detection rate was 51%. Cholelithiasis, dilated biliary ducts, the liver metastases were associated findings. Percutaneous cholangiography in jaundiced patients revealed the level of bile duct occlusion and often suggested the diagnosis. Radionuclide hepatobiliary imaging simply revealed non-visualization of the gallbladder.
