Reason: R/o TIA History: R-sided weakness with dizziness, transient The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. These were present on the prior exam and are unchanged Incidental note is made of cavum septum pellucidum and cavum vergae.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 some mucosal thickening along the right maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. The distance between the interzygomatic line and the is anterior aspect of the cornea and is 19 mm.
Periventricular and subcortical white matter signal changes of a mild degree are present which are nonspecific. These are somewhat atypical at this age group but not substantially different than on the prior exam They could be vascular related, related to demyelination, trauma, vasculitis, sarcoid. They are nonspecific.
