Spurling maneuver. Cervical magnetic resonance imaging (MRI) demonstrated persistent right C5-6 foraminal stenosis and lateral disc protrusion [Figure 1]. She underwent a C5-C6 ACDF performed under microscope visualization.
Postoperative T2 FLAIR axial brain magnetic resonance imaging (MRI) (panel a), DWI axial brain MRI (panel b), and SWI axial brain MRI (panel c) sequences demonstrating no structural, demyelinating, infarct, or hemorrhagic etiology of the patient's transient internuclear ophthalmoplegia.
