肾上腺髓脂瘤的CT诊断

目的:探讨肾上腺髓脂瘤的CT特征,以提高其CT诊断水平.方法:由两位有经验的放射学医生共同回顾性分析18例经手术病理证实的肾上腺髓脂瘤的CT表现,并达成一致意见.结果:多脂肪型11例,少脂肪型7例.7例合并钙化,2例合并出血,13例增强扫描无明显强化.CT诊断符合率为88.9%.结论:CT对肾上腺髓脂瘤的诊断具有较高的敏感性和特异性,其内的脂肪成分有利于诊断与鉴别诊断.

CT Diagnosis of Adrenal Myelolipoma

Objective:For improving the CT diagnostic accuracy of adrenal myelolipoma (AML),CT features of the disease were studied.Methods:The CT findings of 18 surgically and pathologically proven cases of AML were retrospectively analyzed.The CT findings of the 18 cases of AML were studied in a double blind manner and a consensus of the diagnosis of AML was independently made by 2 experienced radiologists.Results:Among the 18 cases of AML,more tumor components of fat were found in 11 cases,while in the other 7 cases less tumor components of fat were shown.7 cases with calcification and 2 cases complicated with hemorrhage were noted.No obvious contrast enhancement on postcontrast scans in 13 cases was demonstrated.The CT diagnostic compatibility rate was 88.9%.Conclusion:CT diagnostic sensitivity and specificity of AML were rather high,and the tumor component of fat was beneficial to the establishment of accurate diagnosis and differential diagnosis.
