目的：探讨原发性中枢神经系统淋巴瘤的MRI表现特征，提高诊断及鉴别诊断水平。方法回顾性分析11例经手术病理及穿刺活检证实的原发性中枢神经系统淋巴瘤的MRI表现。结果单发10例，多发1例，额叶3例，颞叶3例，顶叶2例，脑室旁2例，基底节区1例，11例肿瘤均明显强化，10例肿瘤形态不规则，9例强化均匀，2例可见囊变或坏死。8例肿瘤可见“尖角征”、“脐凹征”及特征性的“蝴蝶征”。结论肿瘤信号均匀，形态不规则，明显强化及出现“尖角征”、“脐凹征”、“蝴蝶征”时可考虑原发性中枢神经系统淋巴瘤。

Objective To explore MRI manifestations and characteristics of primary central nervous system lymphoma in order to improve diagnosis and differential diagnosis. Methods A retrospective analysis was conducted on MRI manifestations of 11 cases of primary central nervous system lymphoma confirmed by surgery, pathology and needle biopsy. Results Ten cases of solitary lymphoma and 1 case of multiple lymphoma were observed. The lymphoma was located in the frontal lobe for 3 cases, the temporal lobe for 3 cases, the parietal lobe for 2 cases, the periventricular area for 2 cases, and the basal ganglia area for 1 case. All of the 11 cases demonstrated obvious enhancement. 10 cases had irregular tumor shape, 9 cases had homogenous enhancement and 2 cases had cystic change or lesion. Cusp sign, dent depression sign and specific feature of butterfly sign were observed in 8 cases. Conclusion Primary central nervous system lymphoma should be considered when there is homogenous signal, irregular shape, obvious enhancement and cusp sign, dent depression sign and butterfly sign.
