Correlation between Arterial Vascularity by Radiologic Study and Structural Histopathologic Type in Resected Hepatocellular Carcinoma(HCC)
Abstract
- PURPOSE
To analize the correlation between dynamic vascular pattern and structural histologic type of HCC.
MATERIALS AND METHODS
The materials consisted of 35 cases of HCC, which could be classified by structural
histologic type and had available preoperative arterial dominant images. Excluding one case of
pseudoglandular type, we compared structural histologic type of the tumors(trabecular group;13 cases, mixed
group;10 cases, and nontrabecular group ;11 cases) with dynamic vascular pattern such as degrees of tumor
staining, severity of tumor vessels on hepatic angiography, and with enhancing degrees of early phase relative
to late phase on two-phase incremental bolus dynamic CT.
RESULTS
In hepatic anglogram, trabecular group showed stronger tumor staining and more prominant
dilatation and irregularity of tumor vessels than those of nontrabecular group, and In two-phase incremental bolus
dynamic CT, and trabecular group showed more prominant tumor enhancement in early phase than those in
late phase.
CONCLUSION
The trabecular type(typical) and non-ti'abecular type of HCC showed radiologically different
vascular patterns and therefore we believe that this maybe the basis with which diagnosis and treatment policy
of radiologically atypical HCC could be made.
