Combined Facial and Abducens Nerve Palsy in Pontine Infarction

ABSTRACT

Isolated cranial neuropathies involving the facial nerve are very rare manifestations of pontine infarction, and have not been described in paramedian pontine infarction. We report a 67-year-old woman who developed sudden and long-lasting right facial nerve paralysis accompanied by transient ipsilateral abducens nerve palsy. Brain magnetic resonance imaging showed two discrete simultaneous infarctions in the right inferior paramedian pontine area, which seemed to correspond to the facial nerve fascicle and the abducens nerve fascicle, respectively. Paramedian pontine infarction can be one of the causes of facial nerve palsy and present as an isolated or predominant sign.
