A case of bilaterally horizontal gaze palsy with facial palsy caused by tegmental pontine infarction / 中华神经科杂志

ABSTRACT

Internuclear ophthalmoplegia mainly affects the horizontal movement disorder of the eyeball. "One and a half syndrome" is characterized by a combination of one eyeball on the affected side cannot be adducted and abducted, and the other eyeball cannot be adducted, but can be abducted accompanied by horizontal nystagmus due to the lesion of tegmental pontine. At present, articles have successively reported "eight and a half syndromes""nine syndromes""thirteen and a half syndromes" and so on. The rapid identification of "one and a half syndrome" spectrum is helpful for clinicians to make right positioning and clinical decision-making. A case of bilateral peripheral facial paralysis with bilaterally horizontal gaze palsy caused by pontine dorsal tegmental lesions is now reported, so as to improve the understanding of the anatomical location and heterogeneity of pontine lesion.
