Anton's Syndrome Presenting as Vertigo

Abstract

Anton's syndrome is a rare cause of vertigo. Its diagnosis may be hindered by confabulatory claims of normal vision by the patient. Any cause of cortical blindness may result in Anton's syndrome, the commonest being a posterior circulation stroke. Here, we highlight a case of Anton's syndrome that was a result of a left vertebral artery thrombosis, presenting initially with vertigo. The patient had a background of previously undiagnosed bilateral posterior communicating artery and right vertebral artery hypoplasia.
