Abstract
Eight-and-a-half syndrome is a rare neuro-ophthalmological condition caused by a focal brainstem lesion involving the paramedian pontine reticular formation (PPRF), medial longitudinal fasciculus (MLF), and ipsilateral facial nerve fascicle¹. We report a 60-year-old diabetic-hypertensive male with right eight-and-a-half syndrome and contralateral cerebellar ataxia due to a subacute infarct in the right hemipons extending to the pontomedullary junction. The case illustrates a classic example of clinico-radiological correlation and
emphasizes the role of early neuroimaging.
