[Horizontal gaze palsy due to lesion of the abducens nucleus detected with magnetic resonance imaging].
A case of unilateral horizontal gaze palsy is reported. The lesion of the abducens nucleus was clearly detected with magnetic resonance imaging. In the early stage, the adduction of the right eye and abduction of the left eye were completely limited and the vestibulo-ocular reflex was also impaired. However, during the recovery stage, the improvement of limitation of abduction was delayed compared with that of adduction. We suggest that this phenomenon is useful as a differential diagnosis between lesions of the abducens nucleus and of the paramedian pontine reticular formation.
