 Brain MRI: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. Mucosal thickening is present within the right maxillary sinus as well as a few scattered bilateral ethmoid air cells. Remaining paranasal sinuses and mastoid air cells are clear. Brain MRA: 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 or aneurysms are identified. No arteriovenous malformations are identified and there is no evidence for cerebral vasculitis. Brain MRV:There is normal venous flow demonstrated within the internal cerebral veins, vein of Galen, straight sinus, superior sagittal sinus and within the bilateral transverse and sigmoid sinuses. No dural venous sinus thromboses or occlusions are identified.
1.Mucosal thickening is present within the right maxillary sinus as well as a few scattered bilateral ethmoid air cells. Otherwise negative MRI of the brain including gadolinium enhancement.2.Negative MRA of the brain.3.Negative MRV of the brain.
