30-year-old female with syncope and question of seizure and right lower extremity hyperreflexia. Evaluate for MS or other central lesion. Artifact limits evaluation on diffusion-weighted images. There is no evidence of intracranial hemorrhage, mass or edema. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or mass effect. The cerebellar tonsils are minimally low-lying, but display rounded morphologies. The pituitary gland is mildly flattened, which is nonspecific. There are no areas of abnormal signal or abnormal intracranial enhancement. There is no diffusion abnormality or susceptibility artifact. Normal flow-voids are demonstrated in the major intracranial vascular structures. The paranasal sinuses and mastoid air cells are unremarkable. The orbits are unremarkable.
1. No evidence of potential seizure foci or demyelinating lesions.2. The cerebellar tonsils are minimally low-lying, but display rounded morphologies. 3. The pituitary gland is mildly flattened, which is nonspecific.
