Trigeminal sensory symptoms due to midbrain lesions.
Three patients with midbrain lesion are described who showed trigeminal sensory symptoms in the contralateral side. Two with ischemic stroke showed partial oculomotor paresis while the third with probable vascular malformation had trochlear palsy. Considering their clinical manifestations and magnetic resonance findings, their sensory changes are believed to be caused by the involvement of the crossed trigeminothalamic fibers near the ocular motor nuclei.
