 There is a partially empty sella. There is no associated optic nerve sheath ectasia, optic nerve sheath dilatation, optic nerve disc flattening, or 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. 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. Other than minimal mucosal thickening within the inferior right maxillary sinus and a single right ethmoid air cell, the paranasal sinuses and mastoid air cells are clear. There is no abnormal enhancement within the brain.
There is a partially empty sella which can be seen in the setting of idiopathic intracranial hypertension (a.k.a. pseudotumor) versus idiopathic partially empty sella. As is no associated optic nerve sheath ectasia, optic nerve sheath dilatation, optic nerve disc flattening, or a "pinched" appearance of the frontal horns, idiopathic partially empty sella is favored.
