Role and pitfalls of hepatic helical multi-phase CT scanning in differential diagnosis of small hemangioma and small hepatocellular carcinoma

Figure 3 SHHE confirmed by surgery. A. Plain scan demonstrated a hypoattenuating lesion in the right lobe, the edge was unclear (arrow). B. Arterial phase CT scan demonstrates the lesion enhanced homogenously and hecame hyperdense (arrow). C. Portal venous phase CT scan demonstrated the lesion remained hyperdense (arrow). D. Delay phase scan demonstrated the same finding as portal venous phase scan (arrow).
