โœฆ Synopsis


Two patients with hepatic adenomas (HAs) were evaluated using dynamic magnetic resonance (MR) imaging. Findings of conventional MR imaging of HAs have varied according to reports in the literature, and dynamic MR imaging of HAs has not been previously reported. Dynamic MR imaging using Gd-DTPA showed homogeneous enhancement in the early dynamic phase and prolonged enhancement in the late phase in the typical HA of Case 2. The HA of Case 1 contained fibrosis and exhibited delayed enhancement. The opacification of contrast enhancement was homogeneous and did not occur from the peripheral region as is observed in typical hemangiomas. In addition, washout of contrast material was not as rapid as with typical hepatocellular carcinomas (HCCs).
