Fig. 5From: SMARC-B1 deficient sinonasal carcinoma metastasis to the brain with next generation sequencing data: a case report of perineural invasion progressing to leptomeningeal invasionRadiographic images of leptomeningeal progression. Magnetic resonance images of the brain and spine are presented in the axial and sagittal planes, respectively. The tumor metastasized to the subdural space along on the right convexity (a) and the ventral cervical spine (b). Multiple areas of enhancement were present in the thoracic spine (c) and along the nerve roots of the cauda equina (d)Back to article page
