 MRI Brain:There is no evidence of intracranial hemorrhage, mass, or acute infarct. There are two nonspecific T2/flair hyperintensities in the right periatrial white matter which are nonspecific. There is no abnormal brain parenchymal contrast enhancement. There is a punctate area of susceptibility abnormality along the right lateral cerebellum which is nonspecific and possibly related to chronic microhemorrhage or mineralization. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRA Brain: The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are also patent. There is a small left A1 segment and small right P-comm artery which are normal variants. The left P-comm artery is large. The vertebral arteries, basilar artery, and posterior cerebral arteries also are patent with no significant stenosis. No evidence of aneurysms or vascular malformations.MRV Brain:There is a dominant right transverse and sigmoid sinus. The superior sagittal sinus, inferior sagittal sinus, transverse sinuses, sigmoid sinuses, straight sinus, vein of Galen, and internal cerebral veins are patent. There is no evidence of venous thrombosis.
No evidence of acute infarct, hemorrhage or venous sinus thrombosis.
