History of demyelinating disease (ADEM versus NMO). Follow-up exam. Brain:No abnormal signal is seen on the T2, FLAIR or diffusion weighted images. No abnormal enhancement is noted on the postcontrast images. There is no evidence of intracranial hemorrhage, mass or edema. The ventricles and basal cisterns are normal in size and configuration. The expected intracranial vascular flow voids are present.The paranasal sinuses are clear. The visualized mastoid air cells are clear. The orbits are unremarkable.Cervical spine:The vertebral body and intervertebral disc heights are maintained. Alignment is anatomic. Small disc osteophyte complex at C5-6. No significant spinal canal or neural foraminal stenosis.The cord is normal in morphology. There is residual trace foci of increased T2 signal in the anterior right cord at the mid C3 level. Focus of increased T2 signal in the right anterior cord at C6 and C7 is also not significantly changed. No abnormal enhancement is noted on the postcontrast images.
1. Essentially normal MRI brain. No evidence of demyelinating lesion.2. Scattered foci of increased T2 signal within the anterior cervical spinal cord which may reflect a demyelinating process are not significantly changed from prior.
