【摘要】：目的:结合磁共振(MRI)影像新技术,提高头颈部血管外皮瘤(HPC)的诊断准确率。方法:回顾性分析病理证实的17例HPC的MRI表现,其中17例均行扩散加权成像(DWI),10例行磁敏感成像(SWI),5例行血管成像。结果:14例位于颅内,2例位于颈部,1例为颅内及颈部多发肿块。在T1WI呈等或稍高信号,T2WI呈稍高信号;DWI上呈等或稍高信号;血管成像显示2例颅内病灶由颈内动脉供血,1例多发肿块由颈外动脉供血,颈内和颈外静脉引流;SWI均显示肿瘤周边及内部多发的静脉和出血灶;结论:HPC的传统MRI表现具有一些特点,MRI新技术可为诊断和鉴别诊断HPC提供更多依据,具有一定价值。
[Abstract]:Objective: to improve the diagnostic accuracy of hemangiopericytoma (HPC) in the head and neck with a new technique of magnetic resonance (MRI) imaging. Methods: a retrospective analysis of the MRI manifestations of 17 cases of HPC confirmed by pathology, 17 of them were diffusion-weighted imaging (DWI), 10 cases of magnetic sensitive imaging (SWI) and 5 routine angiography. Results: 14 cases were located in the intracranial, 2 cases in the neck and 1 cases of cranium. Multiple lumps in the inner and neck region. T2WI was slightly high signal at T1WI and slightly high signal; DWI was slightly high signal; DWI showed equal or slightly high signal; vascular imaging showed that 2 cases of intracranial lesions were supplied by internal carotid artery, 1 cases of multiple masses were supplied by external carotid artery, internal carotid and external jugular drainage; SWI showed peripheral and internal multiple veins and bleeding foci in the tumor; conclusion: HPC The traditional MRI performance has some characteristics. The new MRI technology can provide more evidences for diagnosis and differential diagnosis of HPC, and has certain value.
