Diagnosis: Hereditary hemorrhagic telangiectasia. Other malformations of cerebral vesselsClinical question: 3T scanner, please evaluate for cerebral AVMsSigns and Symptoms: HHT 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 abnormal enhancing 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, arteriovenous malformation or cerebrovascular occlusion.The anterior communicating artery is identified and is intact. The posterior right communicating artery is intact. There is fetal origin of the left posterior cerebral artery with a hypoplastic left P1 segment. The vertebral arteries are similar in size.
There is no evidence for intracranial arteriovenous malformation.
