Abstract
Internuclear ophthalmoplegia with ipsilateral horizontal gaze palsy is called one and a half syndrome. There are a number of numerical one and a half spectrum disorders. One such syndrome is nine syndrome, which is characterized by one and a half syndrome, ipsilateral lower motor neuron type facial palsy, and contralateral hemiparesis or hemihypesthesia or hemiataxia. Here we describe a case of nine syndrome with left one and a half syndrome, left lower motor neuron type facial palsy, and right hemiataxia.
