摘要:

报道高灌注幕上原发性中枢神经系统淋巴瘤1例。CT表现为双侧半卵圆中心对称性类圆形高密度病变,周边可见大片状水肿。磁共振成像表现为稍长及等T1、稍长及长T2信号影,扩散加权成像病变呈高信号影,表观扩散系数值高于邻近正常脑实质,增强扫描病变明显均匀强化,右侧病变内可见斑片状无强化影,磁共振灌注成像表现为明显高灌注。

关键词: 原发性中枢神经系统淋巴瘤, 磁共振成像, 高灌注

Abstract:

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.

Key words: primary central nervous system lymphoma, magnetic resonance imaging, hyperperfusion
