PDFAbstract
Objective To discuss imaging features of primary central nervous system lymphoma. Methods CT、MR and MRS findings of 14 patients with pathologically proved PCNSL were analyzed retrospectively. Results Imaging feature of PCNSL were as follows: (1) the most common site of involvement was deep brain tissue like the frontal lobes, the corpus callosum and the basal ganglia; (2) high or isodense on CT images, slightly edema around the lesions; (3) high density or isodense on T1-weighted images and isodense or slight high density on T2-weighted images; well-defined; (4) enhancement was obvious and homogeneous; the presence of "incision sign" and "butterfly sign" were more specific. Conclusion Imaging of CT and MR of PCNSL was varied, but has some features. 1 H-MRS could help the diagnosis of PCNSL.
