摘要:
【摘要】目的 探讨CT检查对原发性肾上腺肿瘤的诊断与鉴别价值。方法 对重庆市开州区人民医院2010年1月~2016年6月经手术、病理证实的60例原发性肾上腺肿瘤患者相关资料进行回顾性分析,比较不同肿瘤类型CT表现特征,并测量其平扫、动、静脉期增强扫描CT值。结果 60例原发性肾上腺肿瘤均为单侧病变,皮质腺瘤钙化率与嗜铬细胞瘤比较差异无统计学意义(P>0.05);皮质腺瘤边界清晰、规则形态、均匀密度比率均显著高于嗜铬细胞瘤,差异有统计学意义(P<0.05);增强扫描皮质腺瘤多显示为轻中度均匀强化,嗜铬细胞瘤及皮脂腺癌均为不均匀明显强化,节细胞神经瘤显示轻度不均匀强化2例,无明显强化4例; 皮质腺瘤、嗜铬细胞瘤肿瘤大小分别为100~1071cm、331~1965cm;皮质腺瘤平扫、动脉期、静脉期平均CT值均显著低于嗜铬细胞瘤,差异均有统计学意义(P<0.05)。结论 不同类型肾上腺肿瘤CT征象各异,且因其组织成分各异而呈现不同的CT值,肿块密度、强化程度等可作为原发性肾上腺肿瘤诊断与鉴别的重要依据。

Abstract:
【Abstract】 Objective To investigate the value of measuring CT examination in the differential diagnosis of primary adrenal tumors. Methods The related data of patients with adrenal tumors confirmed by operation and pathology in Chongqing State District People's Hospital between January 2010 and June 2016 were analyzed. The CT findings were compared between different tumor types, and the plain scan was measured. In the second phase, CT value of scan was enhanced. Results All the 60 cases of primary adrenal tumors were unilateral lesions, and the calcification rate of cortical adenoma was 1250%, while that of pheochromocytoma was 3158% (P>0.05); The ratios of cortical adenomas with clear boundaries, regular shape and homogeneous density were significantly higher than those of pheochromocytomas (P<0.05); Enhanced scan of cortical adenomas showed mild to moderate homogeneous enhancement, while pheochromocytoma level cortical adenomas showed inhomogeneous enhancement. Ganglioneuroma showed slight inhomogeneous enhancement in 2 cases, and no enhancement in 4 cases; The sizes of cortical adenoma and pheochromocytoma were 100 ~ 1071cm and 331 ~ 1965cm respectively; The average CT values of plain scan, arterial phase and venous phase of cortical adenoma were significantly lower than those of pheochromocytoma(P<0.05). Conclusion CT findings of different types of adrenal tumors are different, showing different CT values due to various tissue components. The density and enhancement degree of masses can be used for the diagnosis and differential diagnosis of primary adrenal tumors.
