title: Phrygian cap simulating mass lesion in hepatobiliary scintigraphy.
abstract: Hepatobiliary imaging has been used to demonstrate that defects in the region of the gallbladder fossa in sulfur colloid studies correspond to normal gallbladder and not tumor. We report a case of delayed filling of a portion of the gallbladder due to a Phrygian cap anomaly. The case demonstrates that without delayed images incomplete filling of the gallbladder can be confused with a mass lesion in the liver.
