 Brain: There is diffuse global parenchymal volume loss. 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. Punctate focus of susceptibility in the left parietal lobe versus adjacent sulcus is nonspecific, but may reflect a chronic microhemorrhage. Small T1 hyperintense, T2 hypointense focus in the left frontal sinus compatible with a proteinaceous cyst. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. Mild mucosal thickening in the maxillary sinuses and ethmoid air cells. Fluid in the mastoid air cells bilaterally. There is no abnormal enhancement within the brain. Orbits: No abnormal mass or abnormal enhancement is seen. No abnormal signal intensity is evident. The optic nerves are normal in size and signal intensity, and are symmetric bilaterally. No retrobulbar mass, chiasmatic mass, or parasellar abnormality is seen. Extraocular muscles are unremarkable.
No specific findings in the MRI of the brain or orbits to account for the patient's diplopia.
