目的探讨CT对无功能性肾上腺肿瘤的诊断价值。方法回顾分析32例无功能性肾上腺肿瘤的CT表现。结果32例中,皮质腺瘤13例,皮质腺癌2例,转移瘤11例,髓样脂肪瘤4例,囊肿2例。26例为单侧肾上腺肿瘤,6例为双侧,均为转移瘤。各类无功能性肾上腺肿瘤的密度、大小、形态、CT值等方面有相对不同的CT表现特点。结论结合临床表现及肿瘤的CT征象,多数无功能性肾上腺肿瘤均能作出准确的定性诊断。 Objective To investigate the diagnostic value of CT in non-functional adrenal tumors. Methods The CT findings of 32 cases of non-functional adrenal tumors were retrospectively analyzed. Results Of the 32 cases, 13 were cortical adenomas, 2 were cortical adenocarcinomas, 11 were metastases, 4 were myeloid lipomas and 2 were cysts. 26 cases of unilateral adrenal tumors, 6 cases of bilateral, are metastases. Various types of non-functional adrenal tumor density, size, morphology, CT values ​​have relatively different CT features. Conclusion Combined with clinical manifestations and CT signs of tumors, most non-functional adrenal tumors can make accurate qualitative diagnosis.
