Cholescintigraphy in gallbladder carcinoma.

Findings on cholescintigraphy in gallbladder carcinoma are described in five patients. Four patients presenting with acute cholecystitis had nonvisualization of the gallbladder with normal hepatoenteric transit time. One of these had a large portal mass and two had liver metastasis as additional findings. The fifth patient was jaundiced, and showed absence of bowel activity compatible with total biliary obstruction. Both the clinical and scintigraphic findings in gallbladder carcinoma are difficult to separate from findings in cholelithiasis and cholecystitis.
