Dizziness, hyperreflexia, and previous C4-C5 disc herniation. Brain: 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 ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, and scalp soft tissues are grossly unremarkable. However, there is fluid signal in the bilateral mastoid air cells, right more than left. There is a small secretion within the left posterior ethmoid sinus.Cervical Spine: There is a small posterior disc-osteophyte at C4-5 that mildly indents the spinal cord. There is a larger posterior disc-osteophyte complex at C5-6 that indents the spinal cord. There is no significant spinal canal stenosis at the other cervical levels and the spinal cord displays normal signal. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The paravertebral soft tissues are unremarkable.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. Posterior disc-osteophyte complexes at C4-5 and C5-6 with mild indentation upon the spinal cord.
