肾上腺皮质结节性增生与皮质腺瘤的CT鉴别诊断

目的:探讨肾上腺皮质结节性增生与肾上腺皮质腺瘤的CT鉴别诊断.方法:回顾性统计分析31例肾上腺皮质结节性增生与35例肾上腺皮质腺瘤的CT表现,所有病例均经手术及病理证实.结果:结节性增生组与腺瘤组在患者性别、病变位置、病变的边界及同侧肾上腺形态方面存在显著统计学差异(P＜0.05).Logistic回归分析表明,病变边界清楚与否在两者鉴别中具有重要意义.结论:在肾上腺结节性增生与肾上腺腺瘤的鉴别诊断方面CT检查可提供重要参考.结合临床及实验室检查,将会对两者的鉴别提供更大的帮助.

Differential Diagnosis of Adrenal Nodular Hyperplasia and Cortical Adenoma in Multi-detector CT

Objective:To evaluate the differences of multi-detector spiral CT (MDCT) findings between adrenal nodular hyperplasia and cortical adenoma.Methods:The CT features of surgery and pathology proved adrenal nodular hyperplasia (n=31)and adrenal cortical adenoma (n=35) were retrospectively analyzed.Results:There were significant difference in sex,location as well as margin of lesion and the shape of the ipsi-lateral adrenal gland between adrenal nodular hyperplasia and cortical adenoma.Whether the margin of lesion was distinct or vague demonstrated as the main characteristics in the discrimination of these two diseases (P<0.05).Conclusions:CT is helpful in the differential diagnosis of adrenal nodular hyperplasia and cortical adenoma,the diagnosis accuracy will be improved when combined with clinical laboratory examination.
