肝脏局灶性结节增生CT诊断

目的:提高对肝脏局灶性结节增生(FNH)CT表现的认识和术前诊断准确性。方法:回顾性分析6例经手术病理确诊FNH病例的典型和不典型CT表现。结果:6例FNH病例中,4例具有较典型的CT表现:如显示中心疤痕(3例);增强早期明显均匀强化(除外疤痕)(4例);增粗与扭曲的供血动脉(3例)等。另外2例,增强早期明显不均匀强化;疤痕区不明显等,术前被误诊为肝细胞肝癌。结论:通过对典型和不典型FNH病例的平扫和增强CT分析,有助于提高对FNH的CT征象的认识,从而提高FNH术前诊断的准确性。

The CT diagnosis of focal nodular hyperplasia of the liver

Objective:To enhance the understanding of CT findings of focal nodular hyperplasia(FNH) of the liver and to improve the preoperative diagnostic accuracy.Methods:Six cases of FNH confirmed surgical pathologically were collected and its typical and atypical CT findings ware analysed retrospectively.All cases did plain and multiphase enhanced CT examination.Results:In six FNH cases,the four presented the typical CT findings: central scar tissue(3 cases);obvious homogeneous enhancement in early phase(4 cases);dilated tortuous of artery(3 cases).Another two cases with inhomogeneous early enhancement and no central scar ware mistaken as HCC preoperatively.Conclusion:The analysis of typical and atypical FNH cases was helpful to understand CT features of FNH and to increase its preoperative diagnostic accuracy.
