Axial (top) and coronal (bottom) magnetic resonance imaging with contrast of the third cranial nerve at presentation. This shows enhancement (white arrows) in the T1 postcontrast images and increased T2 signal (blue arrow) in the third cranial nerve.

This was reported to show abnormal enhancement with slight thickening of the cisternal segment of the left third cranial nerve (Fig. 1a-d).
Axial (top) and coronal (bottom) magnetic resonance imaging with contrast of the third cranial nerve 10 months after initial presentation. This shows less and only faint enhancement (white arrow) in the T1 postcontrast images and persistently increased T2 signal (blue arrow) in the third cranial nerve.

She had a repeat MRI 10 months later that showed significant improvement with only faint, minimal enhancement at that time (Fig. 2a-d).
