NONCONTRAST CT HEADRedemonstration of the right frontal lobe chronic ischemic infarction. There is no evidence of new acute ischemic or hemorrhagic lesion. Underlying brain shows minimal to mild diffuse brain atrophy with multifocal patchy low attenuations on periventricular white matter indicate age appropriate non specific small vessel ischemic disease. The ventricles, sulci, and cisterns are symmetric and unremarkable. The osseous structures are unremarkable. The paranasal sinuses and mastoid air cells are clear. CTA HEAD AND NECKThere is evidence of right extracranial internal carotid artery endarterectomy with multiple surgical staples and long silastic drain inserted on the right neck. The distal right CCA just below the bulb shows about 10% luminal stenosis. Otherwise right extracranial ICA appears to be patent without showing any evidence of occlusion or intra luminal thrombus. Other extracranial and intracranial arterial sytem appear to be unchanged in terms of atherosclerotic changes since prior exam which include left vertebral artery ostial stenosis, mild to moderate left extracranial ICA stenosis, bilateral distal ICA, especially cavernous sinus segment, wall calcifications and luminal stenosis about 40% and irregular basilar arterial lumen. There is no evidence of intracranial arterial aneurysm. There is normal superficial and deep intracranial venous drainage.
