【摘要】Objective To observe the MRI characteristics of brain parenchyma ependymoma.Methods Clinical,pathological and MRI data of 9 patients with brain parenchyma ependymoma were analyzed restrospectively.All patients underwent plain and dynamic contrast-enhanced MR scan.Results The lesions located at the supratentorium in 5 patients,4 located at the infratentorium,including 3 solid masses and 6 cystic solid masses on plain MRI,all 9 cases manifested as lower,equal or higher signal on T1WI and T2WI.Rosette-like ring enhancement were observed in 3 lesions and irregularly solid enhancement in 6 cases and hemorrhage in 2 cases. Conclusion Brain parenchyma ependymoma has certain characteristic MRI findings which are correlative with pathology.% 目的探讨脑实质室管膜瘤的MRI特征。方法回顾性分析经病理证实的9例脑室外室管膜瘤患者的临床、病理及MRI资料。9例患者均接受MR平扫及增强扫描。结果5例肿瘤发生于幕上，4例肿瘤位于幕下。MR平扫3例为实性，6例为囊实性。9例肿瘤T1WI和T2WI 呈均匀或不均匀低、等、高信号。增强扫描3例肿瘤呈花环样环形强化，6例肿瘤呈不均匀实性强化。其中2例伴出血。结论脑实质室管膜瘤的MRI表现较具特征性，与病理有一定的相关性。 【总页数】3页(163-165)
