目的总结肾上腺髓质脂肪瘤(AML)的CT及MRI影像学表现。资料与方法回顾性分析经手术穿刺病理证实的11例肾上腺髓质脂肪瘤的影像学表现特点。结果11例肾上腺髓质脂肪瘤(AML)中,1例为双侧肿块,共12个病灶,CT表现为含脂肪组织的混杂密度肿块,增强扫描无强化。CT诊断率为100%。1例行MRI检查,表现为右侧肾上腺区可见卵圆形,境界清楚的脂肪样信号强度,T1WI呈不均匀高信号,T2WI呈高信号,脂肪抑制呈不均匀低信号影,增强扫描未见明显强化。结论随着影像学发展,尤其是CT、MR在临床上的广泛应用,使本病的确诊率明显提高。
Objective To summarize CT and MRI findings of adrenal medullary lipoma (AML). Materials and Methods Retrospective analysis of 11 cases of adrenal medullary lipoma confirmed by surgical biopsy pathological features. Results Of the 11 cases of adrenal medullary lipoma (AML), one was a bilateral mass with 12 lesions. The CT showed mixed mass with adipose tissue without enhanced enhancement. CT diagnostic rate was 100%. 1 routine MRI examination, the performance of the right adrenal area can be seen oval, clear the state of fat-like signal intensity, T1WI was uneven high signal, T2WI was high signal, fat suppression was uneven low signal shadow, enhanced scan no seen Significantly strengthened. Conclusion With the development of imaging, especially CT, MR widely used in clinical, so that the diagnosis of the disease was significantly improved.
