43 years Female (DOB:1/11/1973)Reason: r/o aneurysm History: new onset headache with pulsatile swishing in earsPROVIDER/ATTENDING NAME: SANDRA NAAMAN SANDRA NAAMAN MRI of the brainNo diffusion weighted abnormalities are appreciated.The CSF spaces are appropriate for the patient's stated age with no midline shift. The temporal horn of the right lateral ventricle is larger than the temporal horn of the left lateral ventricle.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: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 triplication of the anterior cerebral artery. The posterior communicating arteries are small. The vertebral arteries are similar in size.
1.No evidence for cerebrovascular occlusive disease.2.No evidence for intracranial aneurysm or arteriovenous malformation. Please note that MR angiography is as sensitive as conventional angiography in detection of dural arteriovenous fistula.3.Asymmetry in the size of the temporal horns of the lateral ventricles is a nonspecific finding which could relate to a small cyst in the temporal horn. This could also be considered a variation of normal. The underlying hippocampi appear to be similar in volume on visual inspection.
