A: Postcontrast axial T1 weighted fat saturated images of the brain obtained at the initial presentation to our care demonstrate extensive leptomeningeal enhancement involving the basilar cisterns, cerebellar folia, and sylvian fissures. B: Postcontrast sagittal T1 weighted fat saturated images of the cervical spine obtained at the initial presentation to our care demonstrate extensive nodular leptomeningeal enhancement of the cervical spine as well as two large intramedullary enhancing lesions. Marked T1 hypointensity about the intramedullary lesion in the cervical spine is compatible with surrounding spinal cord edema. Brainstem and cerebellar leptomeningeal enhancement is also redemonstrated.
