Disseminated cat-scratch disease: case report and review of the literature

摘要

Cat scratch disease (CSD) can present as a systemic disease in 5-10% of cases and lead to various disease entities. A previously healthy 16-month-old boy presented with fever for 7 days without other obvious symptoms. Abdominal computed tomography scan demonstrated enlarged right inguinal lymph nodes and multiple small round hypodensities in the spleen. Despite antibiotic treatment for 1 week, the fever persisted and the intrasplenic lesions progressed. Inguinal lymph node biopsy confirmed CSD by immunohistochemistry staining. The diagnosis of CSD was also supported by a history of contact, imaging and serological findings. The patient recovered after treatment with azithromycin for a total of 5 weeks and, in serial follow-up, the hepatosplenic micro-abscesses resolved after 4th months.
