With development of computed tomography, detection of the hepatocellular carcinoma are easily performed and frequently used in the world. During 15 months, from December 1985 to February 1987, 59 patients with hepatocellular carcinoma were evaluated with computed tomography in department of radiology at Wallace memorial baptist hospital. RESULTS : 1. The most prevalent age group were 5the to 7the decaedes. male to female ratio was 4.9:1 2. Classification with incidence of computed tomographic appearance of the hepatocellular carcinoma were solitary type 28 cases, multinodular type 24 cases, and diffuse type 7 cases, Association with liver cirrhosis was noted in 22 cases. 3. Inhomogenous internal consistency of hepatocelluar carcinoma due to central necrosis were 35 cases. Portal vein invasion by hepatocellular carcinoma was noted in 15 cases, and particularly most common in diffuse type 4 cases. 4. On precontrast scan, all hepatocellular carcinoma were seen as area of low dens ty except for 3 cases. of near isodensity which turned out to be remarkable low density on postcontrast scan. 5. In solitary type, posterior segment of right lobe was most common site of involvment 12 cases. In diffuse type, bilobar involvment.
