title: Transient isolated ocular motor abnormality related to perilesional edema of an acute medullary microbleed: A case report and review of the literatures.
abstract: We report a case of transient isolated gaze-evoked nystagmus with ocular lateropulsion in a patient with an acute medullary microbleed which was detected by brain magnetic resonance imaging. Considering the correlation between the neural structures involved by the lesion and the ocular motor symptoms of this patient, we suggest that the perilesional edema of the acute medullary microbleed is responsible for this transient ocular motor abnormality.
