Liver tumors, correlation of computed tomography (CT) and pathology

Journal Article:

Abstract

Computed tomographic and pathologic correlation was studied in 12 autopsied cases with 11 cases of metastatic liver tumors and 1 case of hepatocellular carcinoma. Despite of proliferative patterns of the tumors, nodular low attenuations on CT showed scattered nodular lesions and geographic low attenuations on CT showed groups of multiple small nodular lesions, macroscopically. Abnormal areas of low attenuation were generally diminished by drip infusion contrast enhancement, which was more significant on tumors of infiltrative proliferation. Tumors of infiltrative proliferation revealed little degeneration of surrounding liver cells and abnormal areas of low attenuation were more distinct before contrast enhancement. Tumors of expansive proliferation revealed obvious degeneration of surrounding liver cells and a case having about 200 layers of degenerated liver cells revealed more distinct after contrast enhancement. The central lower density areas in abnormal areas of low attenuation on CT coincided with liquefactive necroses with scanty capillary. vessels and fibrotic changes, histopathologically. But coagulative necroses without decrease of surrouding blood flows were not visualized on CT. CT could not demonstrate the liquefactive necroses in more small nodules than 2 cm in diameter.
