This is a case report of a 54-year-old male, who was admitted twice with transient ischaemic attacks and eventually stroke due to cerebral vasculitis because of an underlying borrelial infection. He did not have any preceding symptoms of neuroborreliosis (Bannwarth syndrome) or erythema migrans. This report underlines the importance of performing a broad neurological evaluation of patients, who present with atypical neurological symptoms.
