Diagnostic Considerations

Cat scratch disease and atypical mycobacteria tend to have a poor response to antimicrobials and a high incidence of nodal abscess formation. Differentiation of these conditions from acute mastoiditis is relatively easy with preservation of the skin crease and the presence of a healthy middle ear.

Besides the conditions listed in the differential diagnosis, other problems to be considered include the following:

  • Tumors
  • Auricular or mastoid trauma
  • Furuncle of meatus of the ear
  • Cervical or postauricular (mastoid) adenopathy
  • Parotitis
  • Basilar skull fracture
  • Cysts
  • Stroke
  • Fever of unknown origin
  • Sepsis
