摘　　要：目的探讨肾上腺髓脂瘤的CT特征及其病理基础,以提高其CT诊断水平。方法对12例经手术及病理学检查证实的肾上腺髓脂瘤患者的临床及影像学资料进行回顾性分析。在CT图像上,观察病变的位置、大小、形态、密度、内部结构及其与周围结构的关系,并结合病理学特征进行分析。结果 12例肾上腺髓脂瘤发生在左侧2例,右侧9例,双侧1例。CT特征表现为以脂肪密度为主的混杂密度肿块。病理学检查显示肿瘤由成熟脂肪细胞和骨髓造血细胞组成。术前CT诊断与术后病理学检查结果符合者为11/12例。结论肾上腺髓脂瘤虽然较为少见,但其病理成分特殊,CT表现极具特征性,结合临床和化验检查,术前完全能够正确诊断。Objective To investigate the CT and pathological findings of adrenal myelolipoma,so as to improve the accuracy of diagnosis.Methods CT manifestations of twelve cases with pathological documented adrenal myelolipomas were retrospectively analyzed.Combined with pathological features,the location,size,shape,density,and surrounding structures of adrenal myelolipomas were evaluated on CT image,respectively.Results Of 12 cases with adrenal myelolipomas,9 cases arose from right adrenals,2 cases from the left,and 1 case involved bilateral adrenal glands.CT features delineated the mixed density masses arising from adrenals,but majority components were fat densities.Pathological examination demonstrated the tumor was composed of mature fat cells and bone marrow cells.Compared with pathologic results,preoperative CT diagnosis was reliable for significant accuracy(11/12).Conclusions Adrenal myelolipoma is rare.Combined with pathological characteristics clinical findings and laboratory tests,adrenal myelolipoma can be correctly diagnosed with CT examination.
