Chiari malformation, pseudotumor cerebri, shunt, drainage from nose possibly CSF fluid, worsening symptoms: back/neck pain, headaches, and fatigue. Brain: There are postoperative findings related to Chiari decompression surgery with an unchanged appearance of the cerebellum. There is mildly constricted cerebrospinal fluid flow across the anterior neo-foramen magnum and paucity flow posteriorly. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a linear T2 hyperintensity that traverses the right frontal lobe and anterior corpus callosum, related to a prior surgical tract. There is a shunt device in position at the posterior craniocervical junction, with susceptibility artifact associated with the reservoir. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, paranasal sinuses, and nasal cavity are grossly unremarkable.Spine: There is no evidence of syringohydromyelia. There is an eccentric left posterior disc-osteophyte complex at T7-T8 that slightly impinges upon the spinal cord. There is mild thoracolumbar scoliosis. There is no evidence of vertebral subluxation, however. The vertebral body heights are intact. An endotracheal tube is in position, with fluid in the surrounding pharyngeal cavity, which may represent secretions.
1. Unchanged postoperative findings related to Chiari decompression, with mildly constricted cerebrospinal fluid flow across the anterior neo-foramen magnum and paucity of flow posteriorly.2. No evidence of syringohydromyelia. 3. An eccentric left posterior disc-osteophyte complex at T7-T8 slightly impinges upon the spinal cord.
