摘要 回顾性分析复旦大学附属中山医院2012年6月至2021年9月经手术病理证实的12例脾脏硬化性血管瘤样结节性转化(sclerosing angiomatoid nodular transformation of the spleen,SANT)的CT特征。研究发现12例SANT患者肿物单发、略低密度、部分边界欠清,病灶平均径均值(49.7±14.2)(24.5~72.5)mm,4例(4/12,33.3%)可见钙化,7例(7/12,58.3%)可见假包膜。动态增强扫描,6例类圆形,6例分叶状。12例病灶均呈渐进性向心性填充式强化(12/12,100.0%)。10例病灶内见结节样强化(10/12,83.3%),6例病灶内见辐轮样强化(6/12,50%),6例病灶(6/12,50%)非辐轮样强化。4例病灶(4/12,33.3%)可见星芒征。本研究显示SANT多表现为脾脏内单发、类圆形肿块,平扫为略低密度,边界不清,可见钙化及假包膜,强化方式均为渐进性向心性强化。强化形态主要为结节样强化,其次为辐轮样强化及非辐轮样强化。
