Overview
Key CT or MRI Findings in Otitis Media
Imaging in otitis media patients will reveal opacification of the middle ear[1]
Acute otitis media
- High Resolution CT scans of the temporal bone in acute otitis media patients may reveal complications, such as the following:[1]
- Acute coalescent otomastoiditis: Findings include mastoid septation and cortex erosion.
- MRI is used for patients with suspected intracranial complications, such as the following:
- Brain abscess
- Sinus thrombosis
- Meningitis
Otitis media with effusion
- For otitis media with effusion patients, contrast-enhanced MRI or CT scan imaging may reveal complete and homogenous middle ear and mastoid cavity opacification.ref name="pmid22695997">Trojanowska A, Drop A, Trojanowski P, Rosińska-Bogusiewicz K, Klatka J, Bobek-Billewicz B (2012).

- A tumor in the nasopharynx may also be revealed as a cause for effusion.
Chronic suppurative otitis media
