雄激素相关肝腺瘤CT及MRI表现

摘要

Objective To evaluate the value of spiral CT and MRI in the diagnosis of androgen-related hepatic adenoma.Methods The CT and MRI data of 22 hepatic adenoma patients who were proved by pathology in Langfang TCM Hospital between December 2009 and June 2017 were retrospectively analyzed.Results Among the 22 patients, 18 had CT scan.The 2 cases of simple hepatic adenoma showed moderate enhancement in one case and strong enhance-ment in one case at arterial phase,and were both hypodense at delayed phase.In the 16 cases of multiple hepatic adeno-mas(148 lesions),there were 9 lesions of no enhancement,11 lesions of slight enhancement,85 lesions of moderate en-hancement,43 lesions of strong enhancement at arterial phase,with 122 lesions of hypointensity and 26 lesions of isoin-tensity at delayed phase.Among the 22 patients,5 had MRI scan,which showed 1 lesion of no enhancement,17 lesions of slight enhancement,4 lesions of moderate enhancement,and 40 lesions of strong enhancement at arterial phase,with 40 lesions of hypointensity and 18 lesions of isointensity at delayed phase.Conclusion The imaging findings of andro-gen-related hepatic adenoma have certain characteristics.CT and MRI scans combined with clinical features are of sig-nificant value in the diagnosis of the disease.%目的 评价螺旋CT和磁共振(MRI)对雄激素相关肝腺瘤的诊断价值.方法 收集2009年12月至2017年6月在廊坊市中医医院行螺旋CT和MRI检查的22例经病理证实的肝腺瘤患者的影像检查资料,对其进行回顾性分析.结果 18例(18/22)患者行CT检查,2例单发肝腺瘤增强扫描动脉期中度及明显强化者各1例,延时期均呈低密度.16例多发肝腺瘤148个病灶中动脉期无明显强化者9个,轻度强化者11个,中度强化者85个,明显强化者43个;延时期呈低密度者122,呈等密度者26个.5例(5/22)患者行MRI检查,增强扫描动脉期无强化者1个,轻度强化者17个,中度强化者4个,明显强化者40个,延时期呈低信号者40个,略高信号者22个.结论 雄激素相关肝腺瘤影像表现具有一定特征,螺旋CT和MRI扫描结合临床特点,对其诊断有重要价值.
