Bannwarth's syndrome and Lyme disease in Finland

Three patients with lymphocytic meningoradiculitis were admitted in 1983-84 to the Department of Neurology, University Central Hospital of Helsinki. Two patients had classical Bannwarth's meningoradiculitis with facial diplegia, and a third patient showed a migrating arthralgia and cardiac involvement compatible with a diagnosis of Lyme disease. Cerebrospinal fluid (CSF) showed initially in all patients a lymphocytic pleocytosis and increased protein with signs of intrathecal IgG synthesis.
