Sažetak
Cat-scratch disease (CSD) is a self-limiting infectious disease characterised with lymphadenopathy in a patient with a history of cat contact. Cases of bone involvement in patients with CSD are rare. We reported a case of 11-year-old boy with prolonged intermittent fever, inguinal lymphadenopathy and osteomyelitis. He had a history of exposure to kittens. The physical examination revealed a febrile boy without an apparent site of infection except an enlarged inguinal lymph node. Its histopathology demonstrated ganulomatous lesion with no presence of acid-fast bacilli. Serum titers for Bartonella henselae were positive. Multiple bone lesions were detected by skeletal scintigraphy. Magnetic resonance imaging (MRI) confirmed and characterised osteolytic masses. The oral combination of azithromycin and rifampicin were given for 6 weeks with a good clinical response. At follow-up, the boy was without symptoms or signs of the disease. Successive MRI controls showed gradual regression of the bone lesions together with significant decrease of acute-phase reactants. In conclusion, CSD should be considered in the differential diagnosis of osteomyelitis. MRI is more reliable for the characterisation, evaluation of soft-tissue extension and follow-up of the bone lesions than scintigraphy. However, the later method permits an overview of the multiple osseous lesions. Therefore, standard MRI equipment may not exclude bone scintigraphy. Both methods are required until whole-body MRI units become routine.
