 A partially empty sella is present. Additionally, there is optic nerve sheath dilatation, although no optic nerve sheath ectasia or MRI evidence of optic disc flattening. There is a suggestion of a "pinched" appearance of the frontal horns.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. Mucosal thickening fills the left maxillary sinus and is also present within left ethmoid air cells as well as left frontal sinus. Fluid is present within a few dependent right mastoid air cells. The remaining paranasal sinuses and left mastoid air cells are clear.

Additionally, there is optic nerve sheath dilatation, although no optic nerve sheath ectasia or MRI evidence of optic disc flattening. There is a suggestion of a "pinched" appearance of the frontal horns. This constellation of MRI features can be seen in the clinical setting of idiopathic intracranial hypertension (a.k.a. Pseudotumor cerebri).
