 MRI brain:The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. There is minimal nonspecific periventricular and subcortical white matter FLAIR signal, which likely represents minimal small vessel ischemic disease. There are no areas of pathological enhancement. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. MRA brain: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, AVM or aneurysm.
MRI and MRA are within normal limits. No vascular lesions associated with HHT are appreciated.
