[Cat scratch disease with bone involvement: a case report and literature review]

Cat scratch disease is an infectious disease caused by Bartonella henselae. Most of the patients present with a lymphadenopathy associated with a local infection at the site of the cat scratch. Disseminated infection is uncommon.

We report an immunocompetent 61-year-old woman who presented with a systemic cat scratch disease including a multifocal osteomyelitis. Diagnosis was confirmed by PCR on the adenopathy. A literature review identified 51 other cases of osteomyelitis associated with cat scratch disease, 14 of those confirmed by PCR.

Bone involvement in cat scratch disease is rare, especially in adults. The diagnosis should be suspected on the basis of patient questioning. The antibiotherapy and the place of surgery are discussed.
