Overview
CT
High Resolution CT scans of the temporal bone in mastoiditis patients may reveal complications, such as the following: [1][2][3]
Acute mastoiditis
- Partial-to-complete opacification of mastoid air cells due to fluid accumulation and thickening of the mucosa that lines the middle ear.
- Erosion of mastoid air cell bony septum
- Mastoid cortex destruction and irregularity
- Periosteal thickening, periosteal disruption,
- subperiosteal abscess.
Sub acute and chronic mastoiditis
Primary imaging findings for chronic mastoiditis include the following:
- Markers for inflammation.
- Sclerosis or opacification of mastoid process
- Tympanic membrane changes: thickening, retraction, tympanic membrane perforation or calcification
- Ossicle erosion or other possible causes for hearing loss.
- Determination of cholesteatoma.
- Intratemporal complications: petrositis, labyrinthitis, subperiosteal abscess, labyrinthine fistula
- Intracranial complications: brain abscess, meningitis
- Presence of fibrous tissue.
- Tympanosclerosis.
- Formation of new bone matter.
- Ossicle erosion and displacement.
- Extension of cholesteatoma to sinuses
