Abstract
Objective To explore the imaging features of patients with primary non-Hodgkin's lymphoma of the central nervous system(PCNSNHL).Methods Clinical data of 12 patients with PCNSNHL were analyzed retrospectively.Results MRI showed equal or lower signal on T 1WI, and equal or higher signal on T 2WI.The space-occupying lesion showed massive homogeneous enhancement and peripheral edema,and the range of edema was disproportionate to lesion size.The dynamic enhanced MRI of space-occupying lesion in early stage showed low signal on T1,high signal on T2.1H-magnetic resonance spectroscopy(1 H-MRS)of 5 cases showed choline(Cho)peak of enhanced regions was significantly increased, and N-acetyla spartate(NAA)peak of enhanced regions was significantly decreased.Conclusions MRI features of PCNSNHL are"sharp angle sign","notch sign"on enhanced T1, or inhomogeneous enhancement.1H-MRS shows choline(Cho)peak of enhanced regions is significantly increased,and N-acetyla spartate(NAA)peak of enhanced regions is significantly decreased,even has lipid peak.关键词
