【摘要】 目的探讨螺旋CT对肾上腺交感神经节的副神经节瘤的定位与定性诊断价值。资料与方法回顾性分析螺旋CT检查后经手术病理证实并有完整病史资料的病例33例。结果起源于肾上腺者30个病灶,肾上腺外4个病灶;其中恶性可能3例,恶性1例;螺旋CT特点有肿块较大,密度不均匀,较大病灶易囊变,增强后肿瘤实质、包膜明显强化,动脉期肿瘤内可见强化的血管影,螺旋CT对该病定位敏感性91.2%,定性正确率94.1%。结论螺旋CT是肾上腺交感神经节的副神经节瘤定位和定性诊断有效的影像学检查方法,可以为手术治疗肿瘤提供详细的解剖学细节。更多还原

【Abstract】 Objective To investigate the value of spiral CT in the localization and qualitative diagnosis of paragangliomas in adrenal and sympathetic ganglia.Materials and Methods 33 cases of paragangliomas examined by SCT with intact clinical information and surgical pathologic results were retrospectively analyzed.Results Adrenal masses were found in 30 cases and ectopic masses of adrenal in 4 cases(multiple mass in 1 case).Of all the cases,3 cases were possibly malignant and 1 case was malignant.SCT findings were of characteristic features:paragangliomas were large in size and inhomogeneous in density,and cystic changes were often seen in large masses,the solid component and envelope of tumors were markedly enhanced after contrast administration,the tumor vessels were displayed in the arterial phase.The sensitivity of SCT diagnosis was 91.2% in localization and the accuracy ratio was 94.1% in qualitative analysis.Conclusion SCT is an effective imaging modality in the localization and qualitative diagnosis of paragangliomas,moreover it can provide more particularly anatomical information for surgery.更多还原
