title: Pelvic osteomyelitis: a diagnostic challenge in children.
abstract: BACKGROUND
  Acute hematogenous osteomyelitis (AHOM) in children usually occurs in tubular bones. Acute hematogenous osteomyelitis of the pelvis is rare and is often not recognized primarily.
  
  
  METHODS
  To review the experience with pelvic AHOM at our institution, we analyzed records from children diagnosed with pelvic AHOM (1984-2003) and compared with those reported in the literature.
  
  
  RESULTS
  Among 220 children with AHOM (median age, 6.4 years), those 19 (9%) with pelvic AHOM were significantly older (median age, 9.0 years; range, 0.04-15.6). All children presented with limping or refused to walk. Twelve of 19 patients were febrile, 16 of 18 had elevated C-reactive protein (>20 mg/L), and 6 of 19 had leukocytes greater than 12 G/L. Staphylococcus aureus was isolated from blood or bone aspirates in 9 of 17 patients, and Streptococcus pneumoniae was isolated in 1. Scintigraphy was diagnostic in 15 of 15 children, and magnetic resonance imaging in 7 of 7 children. The mean time between initial symptoms and diagnosis was 3 days (range, 1-8 days). Infection resolved completely in all children after antibiotic therapy.
  
  
  CONCLUSIONS
  Pelvic AHOM should be considered in children with limping and pain referred to the hip, thigh, or abdomen. Diagnosis by scintigraphy or magnetic resonance imaging followed by local puncture and microbiological workup allows for specific antibiotic treatment and results in an excellent outcome of pelvic AHOM.
