A case of scirrhous type hepatocellular carcinoma evaluated by contrast-enhanced ultrasonography

Abstract

A 68-year-old man with a hepatic tumor presented to our outpatient clinic in 2009. Ultrasonography visualized a 50 mm hypoechoic nodule in segment 6. Contrast-enhanced ultrasonography (CEUS) revealed a hypervascular spoke-wheel-like lesion in the early phase and a heterogeneous lesion in the Kupffer phase. Contrast-enhanced CT revealed enhancement of the mass with a delayed central enhancement pattern. . Contrast-enhanced MRI using Gd-EOB-DTPA showed a heterogeneous, hypervascular mass in the early phase. In the hepatobiliary phase, the mass was hypointense, and another hypointense lesion was seen in segment 2. The two nodules were diagnosed based on the imaging findings as scirrhous type hepatocellular carcinoma. The patient underwent partial hepatectomy and the pathological findings were found to correlate with the imaging.
