title: Bone scintigraphy in children with cat scratch disease.
abstract: OBJECTIVE
  The objective of this study was to evaluate the degree and incidence of bone involvement in patients with cat scratch disease.
  
  
  METHODS
  Patients admitted between 2004 and 2011 at the pediatric department for cat scratch disease and a positive serology for Bartonella henselae were identified. Only those having undergone a bone scintigraphy (BS) were included in this retrospective study.
  
  
  RESULTS
  Sixteen girls and 8 boys with a mean age of 7 years were studied. Bone scintigraphy was positive in 6 (25%), but only 2 had bone pain. Axial involvement was present in all 6 patients, and appendicular lesions in 3 of them. Three patients had a BS control, with improvement or normalization after treatment with antibiotics.
  
  
  CONCLUSIONS
  Bone involvement occurs infrequently in patients with cat scratch disease and is not always associated with specific signs. Cat scratch disease must be suspected in patients with fever of unknown origin presenting multifocal lesions on BS.
