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
