目的：探讨MRI对颅内环形强化病变的诊断价值。方法回顾性分析66例颅内环形强化病变患者的MRI表现。结果66例患者中，肿瘤48例，其中10例良性肿瘤（听神经瘤8例，三叉神经瘤2例）位于鞍区、桥小脑角；25例恶性胶质瘤位于幕上，颞顶枕叶多见；13例转移瘤位于皮髓质交界区。10例脑脓肿，其中细菌性脑脓肿9例，结核性脑脓肿1例。慢性血肿6例，脑囊虫病2例。结论颅内环形强化病变的MRI影像具有不同特点及表现形式，可为临床诊断提供重要依据，并可协助临床制定有效的治疗方案。

Objective To investigate the value of MRI in the diagnosis of intracranial ring enhancing lesions. Methods MRI findings of 66 cases of intracranial ring enhancing lesions were retrospectively analyzed. Results Among the 66 patients,48 had tumors,10 had brain abscess, 6 had chronic haematoma and 2 had cerebral cysticercosis. Among the 48 cases of tumors ,benign tumors were located in the saddle area and cerebellopontine angle in 10 (8 cases of acoustic neuroma and 2 cases of trigeminal neurinoma),malignant gliomas were located in supratentorial,temporal,parietal,and occipital cortex in 25,and metastatic tumors were located in corticomedullary junction in 13.Among the 10 cases of brain abscess,bacterial brain abscess was found in 9 and tuberculous brain abscess in 1. Conclusion Intracranial ring enhancing lesions on MRI images have different characteristics and manifestations , which can provide an important basis for the diagnosis of intracranial ring enhancing lesions and help to develop the effective treatment programs.
