摘要 目的探讨含细胞外脂肪肾上腺腺瘤的CT和MRI影像学特点,提高对该类肿瘤的认识,减少误诊率。方法结合文献回顾性分析7例含细胞外脂肪肾上腺腺瘤的临床、影像学特点及病理资料,7例均行CT平扫及增强扫描,其中4例行MRI平扫。结果 7例含细胞外脂肪肾上腺腺瘤均以非脂成分为主,脂肪呈多灶状分布,3~8个不等,大小约为1.4~7.2 mm。CT显示局灶性脂肪密度影,CT值-110^-46 HU;非脂成分CT平扫值均为5.8~13.4 HU,5例脂肪灶旁见点状钙化影;CT增强扫描呈明显不均匀强化,4例脂肪灶旁见结节状强化,1例脂肪灶旁合并瘤内动静脉血管扩张。4例脂肪灶在T1WI脂肪抑制序列均呈低信号;4例非脂成分在T1WI正相位均为稍高信号,T1WI反相位均为低信号。结论含细胞外脂肪肾上腺腺瘤CT和MRI表现具有特征性,非脂成分的影像特征对该瘤的诊断和鉴别诊断具有重要价值。 Objective To review the CT and MRI findings of adrenal adenoma containing ectocytic fat. Methods Seven patients with adrenal adenoma containing ectocytic fat underwent non-enhanced and enhanced CT scan and 4 of them also underwent non-enhanced MRI examination. Clinical data and imaging findings of 7 patients were retrospectively reviewed. Results Seven cases all had dominant non-fat components. Fatty foci were multiple( 3 ~ 8) with diameters of1. 4 ~ 7. 2 mm. CT values of fatty foci were- 110 ~- 46 HU,while CT values of non-fat components were 5. 8 ~ 13. 4HU. There were calcifications near fatty foci in 5 cases. All cases enhanced heterogeneously. Greatly-enhanced nodules near fatty foci were detected in 4 cases,tumor arteries and veins were dilated in one case. Fatty foci were hypointense on fat-suppressed T1 WI while hyperintense on non-fat-suppressed T1 WI. The non-fat components of 4 cases showed high signal on the in-phase T1 WI with signal dropout on the out-of-phase T1 WI. Conclusion Adrenal adenoma containing ectocytic fat has some characteristics on CT and MRI scanning. Imaging features of non-fat components are helpful for qualitative and differential diagnosis of the tumor.
