Abstract

Pathomorphologic features of 34 cases of hepatocellular carcinoma (HCC) showing hyperechoic pattern among 88 surgically resected HCCs less than 3cm in diameter were studied. The frequency of hyperechoic tumors by tumor size were 11.1% of the tumor less than 1cm in diameter, 44.7% of the tumor ranging 1.1 to 2.0cm in diameter and 39% of the tumor ranging 2.1 to 3.0cm in diameter. The most common features reflecting hyper echogenicity was fatty change (20 cases) and followed by pseudoglandular HCCs (6 cases), peliotic dilatation of blood space (6 cases), sclerotic HCC (1 case), and clear cell change (1 case).
