肾上腺髓质脂肪瘤的CT及MRI诊断

目的：探讨肾上腺髓质脂肪瘤的CT及MRI诊断价值。方法：回顾性分析17例经手术病理证实的肾上腺髓质脂肪瘤的CT及MRI表现。结果：CT扫描显示肾上腺区低密度肿块9例，混杂密度肿块7例，实性肿块1例，8例钙化，1例出血，11例增强扫描无明显强化；4例MRI检查示右侧肾上腺区肿块T1WI、T2WI均呈高信号，结论：CT及MRI在诊断肾上腺髓质脂肪瘤中具有重要价值。

Imaging diagnosis of adrenal myelolipoma

Objective To diagnosis. Methods The imagi pathology were retrospectively study the imaging features of adrenal myelolipoma and differential ng findings of 17 cases of adrenal myelolipoma proved by surgery and analyzed. Results Of 17 cases on CT scan, there were 9 cases of low density mass, 7 cases of confounding density mass, 1 case of parenchyma mass, 8 case of calcification, 1 case of bleeding in the area of adrenal. There was no obviously increase in the density on contrast scan in 11 cases. Four cases examined with MRI showed high signal in T1WI and T2WI in the area of right adrenal. Conclusion CT and MRI scan are very useful in the diagnosis of the adrenal myelolipoma.
