Reason: Evaluate for structural lesions contributing to possible seizures History: paroxysmal LOC \T\ weakness The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a posterior fossa subdural effusion present which is most likely related to atrophyThere are several periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. These are mainly in the right hemisphereNo abnormal 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 basilar artery appears very small. There appears to be fetal origin of the posterior cerebral arteries bilaterally.The visualized portions of the paranasal sinuses demonstrate mucosal thickening and opacification of the right maxillary sinus, right anterior ethmoid air cells and right frontal sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. The eyeball lenses are thin.
1.Periventricular and subcortical white matter changes of a very mild degree are nonspecific. At this age they are most likely vascular related. 2.There is no evidence for acute ischemic infarction
