After a six months history of recurrent headache, nausea, vomiting, an
orectic and depressiv symptoms a 9 year-old boy developed a left-sided
hemiparesis. in his spinal fluid he had an elevated cell-count and al
bumin, positive IgG- and IgM-antibody-titers to Borrelia burgdorferi a
s well as oligoclonal IgG-bands. An MR-scan of the brain showed multif
ocal signs of reduced perfusion on the right side and the EEG showed a
pronounced slowness in right-side activity. The spastic hemiparesis p
artially receded after intravenous penicillin G and supportive physiot
herapy. Similarly documented cases of vasculitic neuroborreliosis in c
hildhood are not often found in the literature. In the presence of uns
pecific symptoms and/or acute hemiparesis one should consider neurobor
reliosis, even in childhood.
