Meningomyeloradiculitis as an Unusual Presentation of Neuroborreliosis in Childhood.

We report a pediatric case of Lyme neuroborreliosis-associated meningomyeloradiculitis with atypical manifestations and negative initial cerebrospinal fluid borrelial antibodies. Transverse myelitis and painful radiculoneuritis have rarely been described in pediatric neuroborreliosis. Clinical manifestations are wide ranging and nonspecific, and the serologic diagnosis is often delayed in the acute phase.
