肾上腺神经鞘瘤的 CT 表现

目的：分析原发性肾上腺神经鞘瘤的 CT 影像学特征。方法收集6例经病理确诊为肾上腺神经鞘瘤患者的临床及影像学资料。结果6例均表现为边界清楚,类圆形或类椭圆形不均质囊实性肿块。其中2例见钙化,3例见分隔。在增强扫描上,肿物均表现为延迟强化。结论肾上腺神经鞘瘤一般表现为边界清楚、密度不均质的类圆形肿块,多合并囊变,分隔及钙化,强化方式多为延迟强化,具有一定的特征性。

CT features of adrenal schwannoma

Objective To analyze computed tomography imaging features of primary adrenal schwannoma.Methods The clinical and radiological data of six cases of adrenal schwannoma confirmed by histopathology were analyzed in this study.Results All six cases of adrenal schwannoma were well-circumscribed,round-like or oval-like,solid and cystic tumors,in which two cases were with calcification,and three cases with septations.On the enhanced CT images,all six tumors displayed progressive enhancement.Conclusion Adrenal schwannoma usually presents a well-defined heterogeneous mass with cystic degeneration,sepations,calcification and characteristic progressive contrast enhancement.
