seizure The CSF spaces are appropriate for the patient's stated age with no midline shift. A small 10x15 cystic lesion anterior to the left temporal lobe associated with mild bone remodeling is present. It follows CSF on all pulse sequences.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate small mucous retention cysts in the maxillary sinuses. The visualized portions of the mastoid air cells demonstrate scattered opacities. The visualized portions of the orbits are intact.
1.Periventricular and subcortical white matter signal changes of a mild degree are present which are nonspecific. They could be vascular related, related to demyelination, trauma, vasculitis, sarcoid. They are nonspecific. 2.Small left middle cranial fossa arachnoid cyst.
