A Rare Case of Q Fever Osteomyelitis in a Child From Regional Australia.

Q fever osteomyelitis is a rare disease. We report an eighth pediatric case from regional Australia. Serology is the first-line diagnostic test, with confirmation by PCR on tissue specimens. In endemic settings, Q fever should be considered in the differential diagnosis of chronic osteomyelitis; in particular, presumed chronic-recurrent multifocal osteomyelitis should be considered a possible presentation of Q fever osteo-articular disease in children.
