TIA vs Seizure. Transient episode of unresponsiveness No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma. No foci of diffusion restriction are appreciated intracranially.There is a moderate degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. Additionally there are small foci of high signal on T2 MRI located in the basal ganglia and thalami many of which represent perivascular spaces in the couple of which do not.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 are clear. 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 moderate degree are nonspecific. At this age they are most likely vascular related. Smaller lesions in the basal ganglia and thalami are present some of which may be related to microvascular events.2.There is no evidence for acute ischemic cerebral infarction.
