Overview

Key CT or MRI Findings in Otitis Externa

  • CT Imaging of malignant necrotizing otitis externa is essential in facilitating diagnosis by proving the extension of infection into the temporal or intracranial bones.[1]
  • Key CT findings in cases of malignant otitis externa include the following:[2]
    • Thickening and enhancing soft tissue in the region of the external auditory canal with or without formation of a phlegmon or abscess.
      • In the case of an abscess, cartilaginous bonering enhancing collection(s) with a low attenuation (necrotic) center can be observed.
    • The route of infection:
    • Destruction of temporal bones and opacified mastoid air cells.
