[Supratentorial Primary Central Nervous System Lymphoma with Hyperperfusion:Report of One Case]

We reported a case of supratentorial primary central nervous system lymphoma with hyperperfusion.Computed tomography revealed hyperdense lesions on the bilateral centrum semiovale with obvious edema.Magnetic resonance imaging demonstrated that the lesion presented slightly long and iso-T1 signal and slightly long and long T2 signals;hyperintensity was found on diffusion-weighted imaging,with relatively high apparent diffusion coefficient value compared with the adjacent normal white matter.Contrast-enhanced imaging revealed bilateral evenly enhanced lesions,along with patchy non-enhanced shadows in right-sided lesion.The perfusion-weighted imaging revealed hyperperfusion in bilateral lesions.
