Unusual Appearance of a Highly Vascular Lesion on Tc-99m DISIDA Hepatobiliary Scintigraphy

Abstract

A lesion was identified on the late images of a hepatobiliary scintigraphic study, but was not detected on the very early images, due to its enlarged blood pool. This combination of scan findings has not been previously described. The implication of the observation is that one must examine all the images of the hepatobiliary study in an effort to detect spaceoccupying lesions of the liver.
