摘要
目的探讨肾上腺外髓性脂肪瘤的CT表现。方法回顾性分析5例经手术病理证实的肾上腺外髓性脂肪瘤患者的CT平扫及增强表现。结果 5例患者中,男4例,女1例。全部病例均为单发病灶,2例病灶位于右侧纵隔,1例位于后腹膜,1例位于肝脏,1例位于盆腔。5例CT平扫均表现为圆形、梭形混杂密度肿块,边界清晰,肿块内见不均匀脂肪密度,4例可见假包膜形成;增强后病灶实性部分轻度或中度强化,脂肪密度无强化。结论肾上腺外髓性脂肪瘤的CT表现具有一定特征性。
Objective To observe CT features of extra-adrenal myelolipoma.Methods Plain and enhanced CT images of 5 patients with extra-adrenal myelolipoma proved by surgery and pathology were retrospectively analyzed.Results Four patients were male and one was female.All of the patients had solitary tumor,2 tumors located in the right mediastinum,1 located in the retroperitoneal space,1 located in the liver and 1 located in the cavitas pelvis.Round or spindle mass of mixed density were observed in plain CT images,sharp border and uneven fat density were showed.Pseudo-capsule was observed in 4 cases.After contrast medium administration,solid component of the masses enhanced slightly or moderately,while the component of fatty density did not enhance.Conclusion CT features of extra-adrenal myelolipoma have certain characteristics.
