Key result
Cerebellar strokes mimic benign labyrinthine lesions with isolated nystagmus and ataxia in ~15% of cases.
Observational (n=39)
Answers are grounded in this paper and cite their sources.
Thirty nine cases of cerebellar infarct and haemorrhage were seen over a period of 3 years. Of these, 69% had no impairment of consciousness. Six cases had nystagmus and gait ataxia as their only abnormal signs. Small cerebellar strokes may present with only vertigo, unsteady gait, and unidirectional nystagmus, thus mimicking labyrinthine lesions. Care in managing vertigo attacks in patients with risk factors for cerebrovascular disease appears to be warranted.

Huang et al. (1985) conducted an observational in Cerebellar infarct and haemorrhage (n=39). Cerebellar infarct and haemorrhage was evaluated on Isolated nystagmus and gait ataxia without impairment of consciousness mimicking labyrinthine lesions. Cerebellar infarct and haemorrhage presented without impaired consciousness in 69% of cases, and 6 of 39 cases had only nystagmus and gait ataxia mimicking labyrinthine lesions.
