Left-sided weakness. MRI: There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma 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. There is a partially empty sella and mild distention of the optic sheaths. Otherwise, the orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRA: There is no flow-limiting stenosis, occlusion or aneurysm. Anatomy at the circle of Willis is conventional.MRV: The right transverse sinus and upper right internal jugular are small/hypoplastic. The major venous sinuses appear to be patent.
1.MRI of the brain is within normal limits. Specifically no evidence of acute infarct. 2.There is a partially empty sella and mild prominence of the optic nerve sheaths, which can be normal variant but also can be associated with intracranial hypertension in the appropriate clinical setting.3.Normal brain MRA. 4.Normal brain MRV.
