颈静脉孔区肿瘤临床表现及影像学分析

目的探讨颈静脉孔区肿瘤的临床特点、影像学特征。方法回顾性分析2006年5月-2009年12月32例颈静脉孔区肿瘤的临床及影像学资料，术前32例患者均行颞骨薄层CT和头颅MRI平扫加增强扫描，22例怀疑颈静脉球瘤患者于术前24dx时内行血管造影和肿瘤供血血管栓塞。32例颈静脉孔区肿瘤有31例行肿瘤全切手术，1例怀疑颈静脉球瘤患者因乙状窦血栓性静脉炎导致患者反复发热未行手术治疗。术后病理诊断颈静脉球瘤21例，神经鞘瘤10例。结果32例颈静脉孔区肿瘤主要临床表现为耳鸣、听力下降和周围性面神经麻痹。颈静脉球瘤的特征性表现为侵蚀性骨质破坏及“盐和胡椒”征：神经鞘瘤表现为压迫性骨质改变、多发囊变并中度强化。结论CT与MRI的合理结合应用，有助于病变的临床诊断和鉴别，有利于下一步手术方案的选择。

Clinical and imaging features of jugular foramen tumors

OBJECTIVE To study the clinical and radiological characteristics of jugular foramen tumors.METHODS The clinical data of 32 patients with tumors of jugular foramen region treated from May 2006 to December 2009 were retrospectively reviewed.All patients were referred to systematic imaging examination of the temporal bone,such as CT(X-ray computed tomography) and MRI(magnetic resonance).Twenty two patients were further examined by angiography and embo1ized 24 hours before operation.Thirty one patients underwen...
