目的 总结颈静脉球瘤的MRI特点 ,评价MRI对颈静脉球瘤的鉴别诊断价值。材料与方法 7例经手术及病理证实的颈静脉球瘤均行MRI平扫与增强扫描 ,对其MRI表现作回顾性分析。结果 6例主要位于颈静脉孔区 ,1例同时见于颈静脉孔区和中耳鼓室。T1WI均呈近肌肉之等信号 ,T2 WI均呈等到稍高信号。所有病灶内均可见流空表现 ,增强后均有明显强化。结论 颈静脉球瘤的MRI表现有较强的特征性 ,为该肿瘤理想的影像学检查方法。
Objective To summarize the MRI features of jugular bulb tumors and evaluate the value of MRI in differential diagnosis of jugular bulb tumors. Materials and Methods Seven cases of jugular glomus tumors confirmed by surgery and pathology underwent plain and enhanced MRI scans, and their MRI findings were retrospectively analyzed. Results The 6 cases were mainly located in the jugular foramen area. One case was found in the jugular foramen area and the middle ear tympanum. All T1WI signals were similar to muscles, and T2WIs showed a slightly higher signal. All the lesions showed empty air performance, and they all had significant enhancement after enhancement. Conclusion The MRI appearance of jugular bulb tumor has strong characteristics and is an ideal imaging method for this tumor.
