摘    要:目的探讨肝局灶性结节增生(FNH)不典型的螺旋CT征象。方法对病理证实或临床确诊的32例FNH患者37个病灶的螺旋CT征象进行回顾性分析。结果 37个病灶中,有 14个病灶直径≤3 cm,23个病灶直径>3 cm;7个病灶周边存在假包膜;22个病灶存在中央瘢痕, 其中有20个病灶直径>3 cm;所有病灶在动脉期均呈高密度,其中31个病灶肿瘤实质均匀强化。结论多发病灶、存在假包膜、无中央瘢痕、动脉期不均匀强化是FNH不典型的CT征象。征象的多样性与病灶的病理类型和病灶的直径相关。

Abstract:Objective To evaluate the atypical helical computed tomography ( CT) features of focal nodular hyperplasia ( FNH). Methods Helical CT images of 32 cases with 37 lesions were reviewed retrospectively which were confirmed as FNH by histopathology or clinic. Results The size of 14 lesions was less than 3 cm, 23 lesions was larger than 3 cm; pseudo capsules were found in 7 lesions; 22 lesions had center scars, the size of 20 lesions among them was larger than 3 cm. The densities of all lesions were higher than those of hepatic parenchyma in hepatic arterial phase, 31 lesions were enhanced homogeneously in hepatic arterial phase. Conclusion Multiple lesions, presence of a pseudo capsule, lacking of central scar, heterogeneous enhancement in hepatic arterial phase are atypical helical CT features of FNH. The various CT features are correlative with the pathologic types and the lesion size.
