【摘要】 目的 探讨肾上腺髓质脂肪瘤的超声及CT诊断价值。 方法 回顾性分析16例肾上腺髓质脂肪瘤患者的超声、CT及临床资料，分析其声像图特点及超声、CT诊断的准确性。结果 17个肾上腺髓质脂肪瘤病灶中，右侧10个，左侧5个，双侧1例。超声表现为均质型强回声11个，强回声区内分布低回声4个，囊实混合性回声1个，1个漏诊，彩色多普勒超声检查上述病灶内均未见明确血流信号。超声和增强CT诊断为肾上腺良性占位的敏感性均为94.1%，诊断为肾上腺髓质脂肪瘤的敏感性分别为23.5%、82.4%，增强CT诊断肾上腺髓质脂肪瘤敏感性明显高于超声(P<0.05)。结论 超声可作为筛选肾上腺髓质脂肪瘤的首选检查和随访观察方法，而增强CT对肾上腺髓质脂肪瘤的定性诊断十分有价值。

    【Abstract】 Objective To evaluate the characteristic features and diagnostic value of ultrasonography and CT on adrenal myelolipoma. Methods The clinical and ultrasound data of 16patients were analyzed retrospectively. Results In 16 patients, 17myelolipoma were found, of which 10 were in right adrenal gland, 5 in left and one patient was bilateral. Internal echoes: 11 cases were homogeneous with high echoes, 4 cases were high echoes with low echoes, 1 cases was high echo with echoless, 1 cases was missed diagnosis. Blood signal were not found in all caseson on color pepoler US. sensitivity of diagnostic ultrasonography and CT on benign tumor of adrenal gland were 94.1%, Sensitivity of diagnostic ultrasonography and CT on adrenal myelolipoma were 23.5%、82.4% respectively, CT obvious surpass ultrasonography in diagnosis of adrenal myelolipoma(P<0.05). Conclusion Ultrasonography is a reliable examination of the first choice and follow-up method for localization and differential diagnosis of adrenal myelolipmal ......
