Hereditary hemorrhagic telangiectasia. Congenital anomaly of cerebrovascular system MRI of the brainThe 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.On T1-weighted imaging there is signal hyperintensity present within the basal ganglia.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, AVM, or cerebrovascular occlusion.The anterior communicating artery is identified. The posterior communicating arteries are not readily identified. The vertebral arteries are similar in size.
1.T1 signal hyperintensity in the basal ganglia raise the question of liver dysfunction or parenteral nutrition. Please correlate with clinical exam findings.2.There is no convincing evidence for arteriovenous malformation or other vascular malformation within the brain parenchyma.
