Abstract:

An ischaemic infarction of the anterior inferior cerebellar artery ( AICA ) is usually associated with vertigo , hearing loss , facial palsy , nystagmus , or truncal ataxia ; it is often accompanied by other brainstem or cerebellar signs . Suddenonset bilateral hearing loss without associated neurological symptoms is infrequent in the literature . We report a case of sudden bilateral hearing loss , later diagnosed as AICA infarction without other symptoms .
