颈部副神经节瘤的DSA诊断研究(附17例分析)

目的 探讨颈部副神经节瘤的ＤＳＡ诊断价值。方法 总结经病理证实的动脉体瘤（ＣＢＴ）１２例、颈静脉瘤（ＣＪＴ）５例，研究ＤＳＡ表现，并与其他颈部肿块性病变进行对照。结果 副神经节瘤主富血供型（ＣＢＴ１１例，ＧＪＴ３例），ＤＳＡ能清楚显示肿瘤血管细节及肿瘤与相邻血管的整体关系。ＣＢＴ颈总动脉分驻开大呈握球状（１２例）、枕动脉近段向前上推移（１２例）、咽升动脉肿瘤中心供血（１０例）具有特征性，３例恶变者

Study of DSA in the diagnosis of paraganglioma of the neck

Objective To evaluate DSA in diagnosis of neck paraganglioma Methods 17 cases with neck paraganglioma underwent surgery and pathology including 12 cases of carotid body tumor (CBT) and 5 cases of glomus jugulare tumor(GJT)were studied with DSA and analyzed Results Paraganglioma is highly vascular DSA could show the details of tumor vessel and relationship with adjacent vessels In CBT the carotid bifurcation opened widely presenting the appearance of griping ball The occipital artery was displaced forward and upward The ascending pharyngeal artery being the feeder was also quite characteristic 3 malignant tumors possessed corresponding DSA features The GJT was located at jugular glomus, usually multicentric and receiving multiple blood supplies from external carotid artery Conclusion The DSA appearances of neck paraganglioma are quite characteristic DSA is the modality of choice for diagnosis and differential diagnosis of neck paraganglioma
