Nonaneurysmal Cranial Nerve Compression as Cause of Neuropathic Strabismus: Evidence From High-Resolution Magnetic Resonance Imaging

Nonaneurysmal motor CN compression should be considered as a cause of CN III and CN VI paresis with neurogenic muscle atrophy when MRI demonstrates vascular distortion of the involved CN. Demonstration of a benign vascular cause can terminate continuing diagnostic investigations and can expedite rational management of the strabismus.
