68 years Female (DOB:8/14/1947)Reason: ro stroke History: ataxiaPROVIDER/ATTENDING NAME: RAYMOND ROOS RAYMOND ROOS MRI of the brainNo diffusion weighted abnormalities are appreciated.The CSF spaces are appropriate for the patient's stated age with no midline shift. 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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. The AP dimension of the left eye is significantly longer than the right eye measures approximately 30 mm whereas right measures approximately 22 mm AP dimension. The left eye is somewhat irregular in shape.Incidental note is made of partial empty sella. Incidental note is made of hyperostosis frontalis interna.MRA brain:Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified and is medium size. The posterior communicating arteries are intact and are medium-sized. The left vertebral artery is larger than the right vertebral artery.MRA neck:There is opacification of the aortic arch, great vessels from the aortic arch and carotid arteries and vertebral arteries. There is no stenosis identified of the great vessels from the aortic arch. On the basis of NASCET criteria there is no significant stenosis at the carotid bifurcations. There is no significant stenosis along the course of the vertebral arteries. Right thyroid lobe is larger than the left thyroid lobe. The thyroid glands are heterogeneous in signal intensity.
1.There is no evidence for intracranial cerebrovascular occlusive disease.2.There is no evidence for extracranial cerebrovascular occlusive disease.3.The left eye is deformed. Please correlate with ophthalmoscopic findings4.The thyroid gland is enlarged and heterogeneous suggestive of a multinodular goiter. Please note that MRA is not accurate in evaluation of the thyroid gland and additional investigation is necessary to confirm the of these findings if clinically appropriate. Please correlate with clinical history.
