Neuro_MR_IAC: 68 F, abducens palsy after MVA.
MRI INTERNAL AUDITORY CANAL AND TEMPORAL BONES WITH AND WITHOUT CONTRAST:
CLINICAL HISTORY: 67-year-old female with right esotropia status post motor vehicle accident concerning for right cranial nerve VI avulsion.
Cerebellopontine angles/IACs: Normal 7th and 8th cranial nerves without evidence of mass or abnormal enhancement.
Fluid spaces of the inner ears: Normal.
Mastoids and middle ears: Normal.
The cisternal portion of the right cranial nerve VI is not visualized
Parenchyma: No acute hemorrhage, infarction, mass, or abnormal enhancement Scattered T2/FLAIR cerebral white matter hyperintensities, nonspecific, likely representing chronic small vessel ischemic disease.
Ventricles and extra-axial spaces: Appropriate for age.
Orbits: Outpouching of the posterior right orbit compatible with a
Atrophy of the right lateral rectus
is again seen.
The right globe is medially deviated
Visualized paranasal sinuses: Clear.
Additional comment: None.
1. The cisternal portion of the right cranial nerve VI is not visualized compatible with avulsion. Redemonstration of sequelae of right cranial nerve VI palsy.
(Traumatic cranial nerve VI avulsion)
