title: Cystic disease of the liver studied by 99Tcm DISIDA and 99Tcm sulphur colloid imaging.
abstract: Two patients with cystic disease of the liver have been studied with 99Tcm sulphur colloid and 99Tcm DISIDA scintigraphy and CT. One patient's cystic lesions are substantially enlarged as seen in 99Tcm sulphur colloid scintigrams performed at 10 year intervals. Another patient's scintigraphic studies performed at 5 year intervals demonstrated no significant progression in the size of the cysts in the liver. The 99Tcm DISIDA scintigram of each patient demonstrated no radiotracer filled-in in the cystic lesions (photon deficient areas on 99Tcm sulphur colloid scan). This finding may be used to differentiate cystic disease of the liver from hepatoma, in which usually DISIDA filled-in the defects seen on the 99Tcm sulphur colloid scintigram.
