摘要

皮质类固醇被广泛用于治疗脑肿瘤患者的瘤周水肿和相关的神经功能缺损。我们描述了一例71岁的胶质母细胞瘤男性患者，在皮质类固醇治疗后，其造影增强降低，此前仅报道过9例。本报告旨在讨论胶质母细胞瘤在类固醇给药和停药后的影像学变化（计算机断层扫描的密度和扩散加权磁共振成像的扩散能力，以及对比增强t1加权磁共振成像的增强）。

Glioblastoma with markedly reduced contrast enhancement after corticosteroid administration: Increased density and reduced diffusion capability are noteworthy

Corticosteroids are widely used to manage peritumoral edema and associated neurological deficits in patients with brain tumors. We describe the case of a 71-year-old male patient with glioblastoma in which contrast enhancement decreased on radiographic imaging following corticosteroid administration, which has been reported previously in only 9 cases. This report aims to discuss radiographic changes in glioblastoma (density on computed tomography and diffusion capability on diffusion-weighted magnetic resonance imaging, in addition to enhancement on contrast-enhanced T1-weighted magnetic resonance imaging) following steroid administration and also following steroid discontinuation.
