 The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. Note is made of a partially empty sella without other imaging features suggestive of idiopathic intracranial hypertension. 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 otherwise negative contrast enhanced MRI of the brain and orbits. Specifically, there are no MRI findings to explain the patient's visual symptoms. Present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain. The optic nerves, chiasm, and tracts appear normal. There is no optic nerve sheath dilatation. The extraocular muscles are normal and symmetric with physiologic, homogeneous, and intense contrast enhancement. The globes appear normal with physiologic enhancement of the ciliary bodies and choroid. No retinal detachment or vitreous clouding. The lacrimal glands are symmetric and within normal limits for size. No orbital mass lesion. No enhancing pathology.
