title: Cat scratch disease presenting as acute mastoiditis.
abstract: OBJECTIVE
  To present the first published case of Cat Scratch Disease presenting as acute mastoiditis and review the relevant literature to discuss the Otolaryngologic manifestations of this disease and its treatment.
  
  
  METHODS
  A case report and literature review of the Otolaryngologic manifestations of Cat Scratch Disease.
  
  
  METHODS
  A case report of a clinical scenario followed by a standard literature review. PubMed, EMBASE, and Cochrane database were used to find articles related to the Otolaryngologic manifestations of Cat Scratch Disease.
  
  
  RESULTS
  A 6 year-old female presented to the Otolaryngologist with the typical appearance of acute mastoiditis. CT Scan confirmed breakdown of the osseous septae of the mastoid and mastoidectomy was undertaken. Granulation tissue and infected lymph nodes adjacent to the mastoid cortex were positive for Cat Scratch Disease. The patient was treated expectantly and recovered uneventfully.
  
  
  CONCLUSIONS
  This is the first literature report of Cat Scratch Disease presenting as an acute mastoiditis.
