About this episode
Contributor: Jared Scott, MD Educational Pearls: Cerebellar strokes make up a disproportionate number of missed or delayed diagnosis for stroke likely due to the subtle nature of the presentation Cerebellar strokes can present with vomiting, dizziness, and ataxia. Unlike anterior circulation stroke, exam findings in a cerebellar stroke are ipsilateral to the lesion On neuro exam, findings may include: Dysmetria: lack of coordination with overshooting/undershooting intended position of limb Dysdiadochokinesia: difficulty with rapid alternating movements Ataxia Nystagmus Consider a cerebellar stroke in patients presenting with vomiting and dizziness without an alternative diagnosis References Edlow JA, Newman-Toker DE, Savitz SI.
