Focal nodular hyperplasia(FNH) is a benign tumor-like lesion of the liver. The telangiectatic type is an atypical histologic variant of FNH, and descriptions of its radiologic findings are rare. We report a case of telangiectatic FNH. A 26-20 mm round lesion was found in the lateral segment of the liver. Although this lesion appeared similar to cavernous hemangioma with rapid intratumoral contrast material enhancement on cross-sectional images, its signal intensity decreased on T2-weighted imaging after the administration of superparamagnetic iron oxide(SPIO), and its appearance differed from that of cavernous hemangioma.
局灶性结节性增生（FNH）是一种肝脏的良性肿瘤样病变。毛细血管扩张型是FNH的一种非典型组织学变异型，关于其影像学表现的描述很少。我们报告一例毛细血管扩张型FNH。在肝脏外侧段发现一个26 - 20毫米的圆形病变。尽管该病变在横断面图像上表现类似于海绵状血管瘤，肿瘤内对比剂快速强化，但其在注射超顺磁性氧化铁（SPIO）后T2加权成像上信号强度降低，且其表现与海绵状血管瘤不同。
