1 A 67-year-old man with intraorbital, infraorbital nerve, and frontal nerve lesions.
A 67-year-old man with intraorbital, infraorbital nerve, and frontal nerve lesions. A, Coronal T2-weighted image shows multiple hypointense nodules in the bilateral orbits, both inside and outside the muscle cone (arrowheads). Bilateral infraorbital and frontal (arrowheads) nerves show concentric thickening. B, Coronal gadolinium-enhanced fat-suppressed T1-weighted image shows marked enhancement of the lesions. Enhancement and concentric thickening of bilateral infraorbital (arrows) and frontal (arrowheads) nerves are noted. C, Axial gadolinium-enhanced fat-suppressed T1-weighted image shows diffuse concentric thickening of bilateral frontal nerves (arrows). K. Toyoda et al.
