A Rare Presentation of Posterior Circulation Strokes: A Case Report of Nine Syndrome.

Nine syndrome is a rare variant of one-and-a-half syndrome that results from a stroke in the posterior circulation, mainly manifesting as ipsilateral horizontal gaze palsy, facial palsy, and contralateral hemiataxia. Awareness of the clinical signs of this syndrome is crucial for accurate localization of the lesion and guiding further investigations. We report a case of nine syndrome presenting with signs of one-and-a-half syndrome, ipsilateral facial nerve palsy, hemiataxia, and hemiparesis. There are only a few cases of nine syndrome reported in the literature.
