目的：分析肝脏局灶性结节增生（FNH）的CT特征，以提高本病CT诊断水平。方法回顾性分析23例经病理证实的肝脏局灶性结节增生（FNH）的临床资料和CT表现。23例全部行CT 平扫及三期增强扫描。结果23例FN H均为单发肿块，位于肝脏包膜下16例，突出肝脏表面呈外生性生长7例。大小11mm ×13mm～45mm ×50mm ；圆形或卵圆形21例，不规则形2例。23例 FN H平扫均呈低密度影，15例密度均匀；8例密度不均匀。增强扫描：23例FNH动脉期明显强化，2例动脉期CT值接近同层面腹主动脉CT值，门静脉期和延迟期呈相对高和等密度22例，呈“快进慢出”的强化特点。14例肿块中央见裂隙状疤痕，疤痕呈缓慢渐进性强化。9例FN H肝门侧见增粗迂曲血管影，2例肿块中央见增粗迂曲血管影。结论 FNH的CT表现较具特征性，CT表现对本病的诊断和鉴别诊断具有重要价值。

Objective To increase the preoperative diagnostic accuracy by analysing the computed tomography (CT ) fea-tures of focal nodular hyperplasia (FNH) .Methods CT images pre-and post-3-phase dynamic enhancement in 23 patients were analyzed retrospectively .All cases were proved FNH with pathology .Results All FNH were solitary lesions ,16 le-sions were under liver sub-capsule ,7 lesions were exophytic growth .The size of lesions ranged from 11 mm × 13 mm to 45 mm × 50 mm .21 were spherical or oral and 2 were irregular .On plain scans ,the lesions were all shown hypodensity .15 were heterogeneous ,8 were homogeneous .On enhanced scans ,23 were marked enhanced in arterial phase .The CT values of lesion were isometric with adominal aorta’s in 2 lesions .22 lesions remained slightly hyperdense or turned to isodense in the protal venous phase and delayed phase .The character was“fast in and slow-out”.Star shaped central scars was found in 14 lesions ,central scars were shown delayed enhancements slowly .9 FNH were shown dilated and tortuous arteries at the peripheral area ,2 FNH were in the center .Conclusion MSCT is very useful in diagnosing and differentiating FNH because MSCT scaning is relatively characteristic in FNH .
