 The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. There are no areas of abnormal signal or pathological enhancement. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. There is mild scattered fluid opacification of left greater than right mastoid air cells. Focal plaque like probable dural mineralization is present along the posterior falx. There is a left-sided concha bullosa.CERVICAL SPINE
1.Unremarkable contrast enhanced MRI of the brain, without evidence of demyelinating disease or other acute intracranial process.2.No definite cord abnormality to suggest demyelinating disease.3.Developmental narrowing of the cervical spinal canal with superimposed lower moderate spondylotic changes, most conspicuous at C6-C7 where there are prominent bilateral paracentral disc protrusions resulting in moderate-severe central spinal canal stenosis and severe deformity of the cord. There is also moderate-severe left foraminal narrowing at this level.4.Incompletely visualized thyroid gland, although visualized portion appears enlarged without focal lesion identified. Please correlate with thyroid function tests and thyroid ultrasound may be obtained as clinically indicated.
