Identify the cerebellar artery involved and potential brainstem deficits in a patient presenting with vertigo, ataxia, and dysarthria.

The cerebellar arteries involved could be the Posterior Inferior Cerebellar Artery (PICA), Anterior Inferior Cerebellar Artery (AICA), or Superior Cerebellar Artery (SCA), with either side potentially affected. Key diagnostic features include vertigo, ataxia, and dysarthria, often accompanied by ipsilateral Horner's syndrome or contralateral sensory deficits. Clinical pearls include recognizing that PICA strokes can mimic lateral medullary syndrome, while AICA strokes may present with hearing loss. A common pitfall is confusing these with peripheral vestibular disorders.
