title: The aberrant gallbladder: angiographic and radioisotopic considerations.
abstract: There are four types of aberrant gallbladder: (1) intrahepatic, (2) left-sided, (3) transverse, and (4) retrodisplaced. Five cases of the first three types are illustrated. In three of the five patients the aberrant gallbladder produced false positive liver scans which were correctly diagnosed by hepatic angiography; in one it caused the hepatic angiogram to be misinterpreted. The importance of identifying the gallbladder at hepatic angiography by observing the cystic arteries in arterial phase and the gallbladder wall stain in hepatogram phase is stressed.
