Abstract：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 confirmed 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 calcification 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 findings, which can be helpful in improving the sensitivity and accuracy of imaging diagnosis.
