47 years Male (DOB:12/31/1968)Reason: 3T scanner, please evaluate for AVM History: HHT, at risk for cerebral AVMsPROVIDER/ATTENDING NAME: ISSAM A. AWAD ISSAM A. AWAD MRI of the brainNo diffusion weighted abnormalities are appreciated.There is a developmental venous anomaly present in the right cerebellar hemisphereThe 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.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.MRA brain:There is no arterial supply identified to the patient's right cerebellar developmental venous anomaly.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. There is fetal origin of the left PCA. The LVA is larger than the RVA.
1.No evidence for cerebrovascular occlusive disease.2.DVA right cerebellar hemisphere. 3.No convincing evidence for intracranial aneurysm or AVM based on this exam.
