Unspecified convulsions [R56.9], Reason for Study: ^Reason: New onset seizures, history of lung ca History: New onset seizures Motion artifacts degraded image quality.No evidence of acute ischemic or hemorrhagic lesion.There are scattered FLAIR/T2 high signal intensity lesions mainly on the left frontal and parietal convexity as well as right parietal lobe especially subcortical white matter which do not show any evidence of contrast enhancement. A couple of scattered FLAIR/T2 high signal intensity lesions on bilateral deep white matter lesions are also seen. Constellation of above findings are non-specific. Differential diagnosis include inflammatory lesions including ADEM, toxic encephalitis, post seizure activity changes, unusual PRES but less likely tumor related findings.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. Multifocal bihemispheric (left more than right) subcortical white matter lesions as described above. Differential diagnosis include inflammatory lesions including ADEM, toxic encephalitis, post seizure activity changes, unusual PRES but less likely tumor related findings.
