目的：探讨原发性中枢神经系统淋巴瘤的MRI影像学表现，以提高对该病的诊断准确率。方法回顾性分析8例经手术及病理证实的原发性中枢神经系统淋巴瘤患者的MRI影像学资料。结果本组8例患者共14个病灶，其中4例为单发病灶，4例为多发病灶。病灶部位包括额叶、颞叶、岛叶、枕叶、胼胝体、侧脑室周围脑白质、脑室室管膜及室管膜下、小脑蚓部，且多位于幕上，仅1个位于幕下。MRI显示T1WI呈等或低信号、T2WI呈等或略高信号，仅1例病灶合并出血、2例有囊变，均未见钙化，瘤周均有水肿，增强扫描呈明显均匀强化。结论原发性中枢神经系统淋巴瘤的MRI表现具有特征性，掌握其MRI特点有助于提高诊断的敏感性及准确性。

Objective To explore the MRI manifestations of PCNSL (Primary Central Nervous System Lymphoma) so as to raise the diagnostic accuracy of the disease. Methods The MRI data were retrospectively analyzed in 8 cases of PCNSL which had been conifrmed by surgery and pathology. Results A total of 14 lesions were found in 8 patients, including the single lesion in 4 patients and multi-focal lesions in 4 patients. The locations of the lesions were frontal, temporal lobe, insula, occipital lobe, corpus callosum, periventricular white matter, ependymal surfaces and the cerebellar vermis, most of which were located in the supratentorial region, only 1 lesion located in the infratentorial region. T1WI showed iso-intense/hypo-intense;T2WI showed iso-intense/hyper-intense. Only one case was accompanied with hemorrhage;two cases with cystic changes. No calciifcation were revealed. Both cases were found with peritumoral edema and the mass showed strong homogeneous enhancement by enhanced scanning. Conclusion PCNSL had its characteristic MRI ifndings, which can be helpful in improving the sensitivity and accuracy of imaging diagnosis.
