Right subhepatic abscesses detected by technetium liver scans

A focal defect at the inferior margin of the right lobe of the liver was found in two patients with subhepatic abscesses. This defect must be differentiated from the porta hepatis and the gallbladder fossa. When technetium liver scans are obtained in patients with usspect abdominal abscesses, the inferior margin of the right lobe of the liver should be carefully scrutinized so that righ subhepatic abscesses will not be overlooked.
