Cat-scratch disease is a bacterial infection caused by Bartonella henselae. Bone involvement is rare. We describe the case of a 7-year-old boy with a systemic form of the disease. He presented with a 15-day history of fever, altered general condition, weight loss and cough, associated with back pain, and right-sided coxalgia. Bone scintigraphy with Tc-99m hydroxymethylene diphosphonate showed spinal involvement, the iliac crest, the right ankle, and the right first metatarsal. Magnetic resonance imaging confirmed these locations. He was positive for anti-Bartonella henselae. The fever regressed before treatment with rifampicin began, and he made a full recovery.

BACKGROUND Bartonella infection is the causative organism of cat-scratch disease (CSD), which typically presents with self-limited localized lymphadenopathy. In HIV-infected patients, Bartonella infection can cause systemic illnesses with significant morbidity and mortality manifesting as bacillary angiomatosis (BA), hepatic peliosis, splenitis, bacteremic febrile illness, and other organ involvement. To the best of our knowledge, there have been no reports of HIV-infected patients presenting with generalized lymphadenopathy caused by Bartonella infection. We report an unusual case of CSD presenting with generalized lymphadenopathy in an AIDS patient with advanced immunosuppression. CASE REPORT A 44-year-old woman with AIDS, advanced immunosuppression, and intermittent adherence to antiretroviral therapy and medical care, presented with cough and increased generalized tender lymphadenopathy. A lymph node biopsy 1 year earlier was non-diagnostic for tuberculosis, fungal infection, and lymphoproliferative disorders. She remained with generalized lymphadenopathy. A repeat biopsy with the addition of Warthin-Starry silver staining suggested the diagnosis of cat-scratch lymphadenitis. She responded well to a long course of azithromycin antibiotic therapy, with the resolution of lymphadenopathy. CONCLUSIONS Cat-scratch disease may present with prolonged generalized lymphadenopathy, an unusual presentation in HIV patients with advanced immunosuppression. Awareness of the possibility of CSD in a similar clinical scenario may prompt early recognition and management of this disease.
