[Neuroborreliosis--not only Bannwarth's syndrome]

Two patients with neuroborreliosis are reported. They had Bannwarth's syndrome combined with encephalitis and myelitis respectively. Both patients recovered following high-dose penicillin treatment. Neuroborreliosis may be complicated with CNS involvement although this may be infrequent. It is important to diagnose neuroborreliosis because of the striking effect of penicillin treatment.
