case_images: An MRI showed recurrence of GBM with multifocal cranial deposits [Figure 2] and spinal MRI showed an intradural extramedullary mass measuring 1.1 x 5.0 cm in anterioposterior (AP) and craniocaudal dimensions at T-5 to T-7 level with significant cord compression [Figure 3].
case_images: (a) Sagittal section T-2 MRI showing lesion at T5-T7 levels resulting in significant cord compression. (b) Axial section T-2 MRI (with magnification tool of PACS) showing an intradural extra-medullary mass compressing the spinal cord
