Abstract
It is known that small hepatocellular carcinoma (HCCs) were usually hypoechoic at
ultrasonography (US). In this study, we analyzed US findings of 42 small HCCs less
than 2 cm in diameter and correlated them with histopathologic findings. US parameters
were tumor size, tumor echogenecity, and morphologic features (peripheral halo, lateral
shadow, posterior enhancement, and mosaic pattern), while histopathologic parameters
were Edmonson grade and microscopic features (coagulation necrosis, interstitial fibrosis,
fatty metamorphosis, sinusoidal dilatation, hemorrhage, encapsulation, and internal
septation). One-third of HCCs was not hypoechoic. Tumor echogenecity and morphologic
features were variable, regardless of tumor differentiation and microscopic features.
In our study, it seemed that US detected histopathologic changes in small HCCs more
frequently than previously known, but none of these US findings could suggest a specific
histopathologic finding in small HCCs less than 2 cm in diameter.
