 There is a small T2 hyperintesity in the right occiptal cortex that is T1 hypointense, with blooming centrally on the gradient echo which may represent prior small infarct with hemorrhagic products. Cerebral cavernous malformation is felt to be less likely. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. There is partial opacification of the left maxillary sinus. The right mastoid air cells are opacified. The The remaining paranasal sinuses are clear. There is no abnormal enhancement within the brain. There is antegrade flow within the distal bilateral vertebral arteries, within the basilar artery, distal bilateral internal carotid arteries and carotid siphons and bilateral anterior, middle and posterior cerebral arteries. No arterial stenoses, occlusions, arteriovenous malformations, or aneurysms are identified.
