Cat-scratch disease with bone compromise: Atypical manifestation

Fever, headache, myalgias and lymphadenopathy are characteristic manifestations of cat-scratch disease but other less common findings are described ill 2 to 10% of cases. We report two children that presented with hepatosplenic abscesses and bone involvement. One child, had multiple areas of increased Uptake in the bone scintigram with a positive serology (IgG > 1/256, IgM slightly positive). The second child had destruction of the L2 vertebral body that compromised the channel and right foramen as visualized by MRI. Ill both cases, bacilli were observed in the bone biopsy by Warthing-Starry stain.
