We report two cases of focal nodular hyperplasia in patients following gadoxetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging confirmed with histopathology. These cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. One case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central scar, mimicking hepatocellular carcinoma. The pathologic examination demonstrated that the two lesions were focal nodular hyperplasia.
我们报告两例经病理组织学证实的钆塞酸二钠（Gd-EOB-DTPA）增强磁共振成像检查后发现的局灶性结节性增生患者。这两例患者在注射钆塞酸二钠后的延迟肝胆期表现出非典型的影像模式。一例表现为完全缺损，另一例表现为外周环状强化且无可见的中央瘢痕，类似肝细胞癌。病理检查显示这两个病变均为局灶性结节性增生。
