Multiple abscesses with osteomyelitis and destruction of both the atlas and the axis in a 4-week-old infant.

Abstract

Case report. To report an unusual case of a 4-week-old infant with multiple abscesses, which propagated to the cervical region and destroyed the C1-C2 vertebrae. Cervical vertebral osteomyelitis involving the atlas and axis in childhood is distinctly unusual, which may lead to the rapid destruction of the vertebral body. Propagation of a retropharyngeal abscess is the major cause of cervical vertebral osteomyelitis. Only a limited number of infant case reports are published, and no case of osteomyelitis with the destruction of both the atlas and the dens axis has been reported previously. A 1-month-old infant with multiple craniospinal and thoracic abscesses was surgically treated. Therapy was completed with antibiotics and immobilization. Follow-up was carried out with magnetic resonance imaging, computed tomographic scans, and functional radiographical diagnostics. The retropharyngeal and thoracic abscesses were surgically removed. The infant was placed in a custom-made fixation device for 8 weeks. Two months later, follow-up functional examination revealed no significant instability of the cervical spine. During a 3-year-long follow-up period, no signs of neurological impairment were observed, neck movements were limited but painless. It is assumed that the remnants of the bony elements of C1-C2 vertebrae and the massive interconnecting postinflammatory scar tissue make some degree of neck movements possible. C1-C2 osteomyelitis is a very rare entity even in children. There is limited experience with treatment, but immobilization of the neck, surgical debridement, drainage, and antibiotic treatment can be recommended. Close follow-up is required to check the reconstitution of affected bones and ligaments, any development of instability, and the necessity of surgical stabilization.
