 The cervical spine is in normal alignment. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal caliber and signal. Minimal degenerative changes are seen in the cervical spine. No significant spinal canal or foraminal stenosis within the cervical spine. No abnormal enhancement.THORACIC SPINE
1. No abnormal intraparenchymal or meningeal enhancement within the brain to suggest intracranial disease. Again seen is CSF collection surrounding the Ommaya catheter with surrounding vasogenic edema in the right frontal lobe and associated mass effect.2. Diffuse abnormal leptomeningeal enhancement involving the cauda equina nerve roots and surface of the lower thoracic cord. This finding is similar to outside MRI from 10/9/2014 and compatible with leptomeningeal disease. No evidence of epidural tumor or masses. No cord signal abnormality.
