EXAM: MRI BRAIN WITH AND WITHOUT CONTRAST INDICATION: Evaluation for transient paralysis COMPARISON: Brain MRI from 1/31/2020 TECHNIQUE: Multiplanar, multisequence imaging of the brain before and after the intravenous administration of 13 mL of Dotarem. FINDINGS: EXTRAAXIAL SPACE: Ventricles appear age appropriate. No midline shift. The basal cisterns are patent, with no downward herniation. No fluid collections, hemorrhage, mass lesion, focal signal abnormality or abnormal enhancement. Signal voids of basilar artery, internal carotid arteries and major venous sinuses are maintained. The sella and pituitary are within normal limits. CEREBRUM: No restricted diffusion or hemorrhage identified. Superficial and deep cortical structures are well formed. Few scattered punctate frontal and parietal subcortical and deep white matter T2 hyperintensities are demonstrated, nonspecific but could be related to conditions such as migrainous angiopathy. No abnormal intraparenchymal masslike enhancing lesion or acute intraparenchymal hemorrhage is identified.. CEREBELLUM: Cerebellar hemispheres and vermis are well formed without mass lesion, signal abnormality, or abnormal enhancement. No cerebellar tonsillar ectopia greater than 5 mm identified. BRAINSTEM: Midbrain, pons, and medulla are well formed without mass, signal abnormality, or abnormal enhancement. SKULL/EXTRACRANIAL STRUCTURES: Paranasal sinuses: Visualized portions are clear. Mastoids/middle ears: Visualized portions are clear. Remainder: Visualized orbits are within normal limits. The scalp and calvaria appear unremarkable.

IMPRESSION:

1. Negative for acute infarction, acute intracranial hemorrhage or enhancing intraparenchymal masslike lesion. No acute intracranial abnormality is appreciated.

2.Few scattered punctate frontal and parietal subcortical and deep white matter T2 hyperintensities are demonstrated, nonspecific but could be related to conditions such as migrainous angiopathy.
