原发性副神经节瘤CT诊断

目的：探讨CT对原发性副神经节瘤的诊断价值。方法：回顾性分析42例经手术病理证实的原发性副神经节瘤患者影像资料,其中29例行平扫加单期增强扫描,13例行平扫加双期增强扫描。结果：全部病例均为单发。32例位于肾上腺,其中右侧20例,左侧12例;10例位于肾上腺外。CT平扫特点为肿块密度不均,常伴有坏死与囊变,增强后病灶实性部分显著强化,延迟扫描肿瘤呈进行性强化。结论：CT检查能很好显示原发性副神经节瘤的部位、形态、大小,是对定位和定性诊断有效的影像学检查方法。

CT diagnosis of primary paraganglioma

Objective：To discuss the role of CT in the diagnosis of primary paraganglioma.Methods：The imaging materials of 42 cases with surgery and pathology-proved primary paraganglioma were retrospectively analyzed.Of these,29 cases had plain and single-phase enhanced CT,13 cases had plain and 2-phase enhanced CT.Results：All of the patients had solitary tumor.The location of tumor were adrenal gland（20 cases.right,n=20;left,n=12）,10 cases had extra-adrenal tumor.The characteristics on plain CT were inhomogeneous in density,often accompanied with intra-tumoral necrosis and cystic changes.The solid components of tumor were markedly enhanced after contrast administration and progressively enhanced on delayed scan.Conclusion：The location,morphology and size of primary paraganglioma could be displayed on CT,which is a helpful imaging modality in the localization and characterization of primary paraganglioma.
