New-onset bilateral leg weakness of unknown etiology currently undergoing work-up with differential including GBS, transverse myelitis, spinal mass, hemiplegic migraine, or trauma. Brain: Many of the sequences are degraded by patient motion. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The lateral ventricles are mildly asymmetric, which can represent a developmental variant. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. There is mild scattered paranasal sinus mucosal thickening.Spine: Many of the sequences are degraded by patient motion. The mild prominence of the central canal throughout much of the thoracic spinal cord is incompletely characterized on this exam. The conus medullaris is located at approximately the L1 level. The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. There is no abnormal enhancement or mass lesions within the spine. The paravertebral soft tissues are unremarkable.
1. No evidence of acute intracranial hemorrhage, mass, or Chiari malformation.2. No evidence of mass lesions in the spine or transverse myelitis.3. The mild prominence of the central canal throughout much of the thoracic spinal cord is incompletely characterized on this exam. Please refer to the recent prior thoracic spine MRI for additional details.
