Wall-eyed bilateral internuclear ophtalmoplegia presenting as monocular alternating nystagmus: a non-epileptic phenomenon in a case of diffuse axonal injury.

A 15-year-old male in a persistent vegetative state due to diffuse axonal injury presented with seizures and spontaneous alternating monocular nystagmus. The cranial MRI revealed diffuse axonal injury involving supratentorial and infratentorial structures, and the splenium of the corpus callosum. The monocular alternating nystagmus was thought to be independent of seizures and occurred as a result of diffuse axonal injury affecting the medial longitudinal fasciculus bilaterally.
