【摘要】：目的探讨颅内纤维瘤的磁共振表现。方法选取我院2012年2月~2014年2月经手术或病理证实的颅内孤立性纤维瘤患者9例作为研究对象,对其行MRI平扫、磁共振扩散加权成像(DWI)及增强扫描,分析病变的影像特点。结果颅内孤立性纤维瘤病例T1WI以低信号、等信号为主,其中低信号4例;等信号4例;高信号1例。T2WI以等高信号为主,其中高信号8例;等信号1例;全部病例均显示了条状低信号。DWI图像显示高信号为主,高信号6例,稍高信号3例;ADC图显示稍低信号。增强扫描动脉期全部病例均明显强化,强化不均匀7例,脑膜尾征2例;2例病变显示粗大迂曲血管。结论颅内孤立性纤维瘤的MRI表现具有一定的特征性,具有一定的诊断价值,为术前诊断提供一定的信息。
[Abstract]:Objective to investigate the MRI findings of intracranial fibroma. Methods Nine patients with intracranial solitary fibroma confirmed by surgery or pathology from February 2012 to 2014 were selected as the study subjects. Mr diffusion weighted imaging (DWI) and contrast-enhanced scanning were used to analyze the imaging features of the lesions. Results the imaging features of intracranial solitary fibroma were characterized by low signal intensity and isointensity on T1WI, including 4 cases of low signal intensity, 4 cases of iso-signal intensity and 4 cases of intracranial solitary fibroma. High signal intensity in 1 case, high signal intensity in 8 cases, iso-signal in 1 case. All cases showed high signal intensity. DWI image showed high signal intensity in 6 cases, high signal intensity in 6 cases, high signal intensity in 6 cases, high signal intensity in 6 cases, high signal intensity in 6 cases, and hypointensity in 1 case. In 3 cases with slightly high signal intensity, the signal intensity was slightly low. All the cases were obviously enhanced in the arterial phase of contrast enhancement, and the enhancement was uneven in 7 cases. The meningeal tail sign in 2 cases showed extensive and tortuous blood vessels. Conclusion the MRI findings of intracranial solitary fibroma have some characteristics and have certain diagnostic value and provide some information for preoperative diagnosis.
