摘　　要：目的 总结脑瘤样炎性脱髓鞘病的影像学特点，探讨影像学诊断对本病的诊断价值。 方法 对9例经病理或治疗证实的脑瘤样炎性脱髓鞘病患者的影像学表现及相关文献进行回顾性分析研究。 结果 9例均显示单发类似肿块样病灶，CT平扫多呈低密度，MRI多为长T1长T2信号，DWI呈稍高信号，增强扫描6例呈开环状强化，1例呈闭环状强化，2例呈斑片状或结节样强化，灶周水肿及占位效应相对较轻。6例经激素治疗后MRI复查病灶均明显变小且强化程度明显减低，DWI信号亦明显减低。 结论 脑瘤样炎性脱髓鞘病有特征性的影像学表现，增强MRI及MRI检查新技术的应用能清晰显示该病的病变特点，对其诊断、鉴别诊断及检测病变的转归情况有重要价值。Objective To study the characteristics of tumor-like inflammatory demyelinating dis- eases aud to investigate imaging diagnostic value in tumor-like inflammatory demyelinating diseases fur- ther. Methods The manifestations of 9 patients with tumor-like inflammatory demyelinating diseases confirmed by pathological assessment and treatment were analyzed retrospectively and relevant literatures were reviewed. Results The single localized tumor-like lesions was presented in all 9 cases. CT scan showed low density. MRI showed long T1, T2 signal, and slightly high signal presented on DWI. Open- ring enhancement was observed in 6 cases; closed-ring enhancement in 1 case; nodular or patchy en- hancement in 2 cases; mild edema round the lesion with mild space occupying effect. By using glucocor- ticoids, MRI scan showed lesions was significantly smaller and enhancement was significantly lower, and DWI signal was lower in 6 cases. Conclusions Tumor-like inflammatory demyelinating diseases has spe- cific manifestation in MRI and CT. Enhanced MRI and the application of new technology of MRI can clearly show the pathological feature of the disease, which has important value for its diagnosis and differ- ential diagnosis to detect lesions outcome situation.
