AI Article Synopsis

  • Cat scratch disease is caused by a Gram-negative bacillus from cat saliva or scratches, presenting primarily as localized swelling or regional lymph nodes.
  • Rare complications can occur, including serious issues affecting the liver and bones, such as hepatic abscesses and osteomyelitis, especially in children with a history of cat exposure.
  • A 2-year-old boy with a severe case was treated successfully with azithromycin and rifampin after showing symptoms like fever and musculoskeletal pain, highlighting the importance of abdominal imaging in diagnostics for this condition.

Article Abstract

is a Gram-negative bacillus transmitted to humans via cat saliva or scratch. Cat scratch disease, the typical clinical manifestation of infection, presents as localized cutaneous or regional lymphadenopathy. Rare, atypical presentations, generally reflecting bloodborne disseminated disease, can include hepatosplenic, cardiac, ocular, neurologic, or musculoskeletal involvement. Here, we present a case of disseminated with hepatic abscesses and associated ischial osteomyelitis in an immunocompetent 2-year-old male patient. Although osteomyelitis is a rare manifestation of infection, it should be included in the differential diagnosis in pediatric patients presenting with fever of unknown origin and musculoskeletal pain, especially in the setting of cat exposure. Hepatic involvement of infection is associated with significant morbidity; therefore, abdominal imaging is critical in the diagnostic workup. This patient was successfully treated after a 6-week course of azithromycin and rifampin, as evidenced by symptom resolution and improved fluid collections on repeat imaging. While most cases of resolve without treatment, in severe or disseminated infection such as this case, antibiotics such as azithromycin and rifampin should be considered for treatment.
