Episode description
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
