Headache and presyncope. Evaluate for vascular malformation. MRI BRAIN: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a right frontal lobe developmental venous anomaly. There is also prominence of the caliber of the superificial cerebral veins in the right anterior temporal and left parietal regions which is of uncertain significance but favored to be a developmental variation. The brain parenchyma otherwise appears unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There are mucus retention cysts in the bilateral maxillary sinuses. The skull and extracranial soft tissues are unremarkable. MRA HEAD: The intracranial internal carotid arteries are normal in course and caliber. The middle and anterior cerebral arteries are unremarkable. The vertebral arteries, basilar artery, and posterior cerebral arteries are normal in course and caliber. There is no evidence of flow-limiting stenosis or aneurysm.
1. MRI of the brain is essentially within normal limits. No evidence of intracranial hemorrhage, infarct, or mass. There is a prominent right frontal lobe developmental venous anomaly which is an incidental finding. There is also prominence of the caliber of the superificial cerebral veins (particularly left vein of Trolard and the right superficial middle cerebral vein) which is of uncertain significance but favored to be a developmental variation. Please note entities such as dural arteriovenous fistula cannot be excluded by MRI and further evaluation could be considered if there is specific clinical suspicion.2. Unremarkable MRA without flow-limiting stenosis or aneurysm.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
