Ten-year review of Danish children with chronic non-bacterial osteitis.

Objectives: To compare clinical characteristics of children with chronic non-infectious osteomyelitis (CNO) with either mono- or multifocal bone lesions, and to report potential advantages of using whole-body MRI.

Methods: A retrospective evaluation of 31 children (19 girls, 12 boys) diagnosed with CNO between 2001 and 2011. CNO was diagnosed as mono-, or multifocal inflammatory bone lesions (osteomyelitis, osteitis, osteosclerosis), duration of complaints more than 6 weeks and exclusion of infection and malignancy.
