Unspecified convulsions [R56.9], Reason for Study: ^Reason: possible epilepsy History: as above There are multifocal bihemispheric supra and infra tentorial asymmetric, mainly subcortical white matter and corpus callosum FLAIR high signal intensity lesions. Most of them are not enhancing on post Gad images but the right superior parietal lobule lesion. There is no evidence of surrounding edema.There is no evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.C Spine MRIThe cervical spine appears to be straightened.The cranial-cervical junction is normal. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The cord signal is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal stenosis, cord compression or myelopathy.
1. Multifocal mainly subcortical white matter FLAIR high signal intensity lesions as described above. Differential diagnosis include ADEM, other post viral infection encephalitis, or other demyelinating disease such as multiple sclerosis which is less likely.2. Normal cervical spine MRI
