ENT · Otology: imaging of cholesteatoma
Sample itemOn high-resolution CT of the temporal bone, which finding is typical of an attic cholesteatoma?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
B. Soft tissue mass with blunting of the scutum and erosion of ossicles
HRCT shows a non-dependent soft tissue mass in the attic with erosion of the scutum, ossicles and sometimes the tegmen. Diffusion-weighted MRI helps in recurrence. Vestibular aqueduct and IAM lesions suggest other pathologies.
Option by option
A. Hyperdense mass in the internal acoustic meatus
An IAM mass suggests vestibular schwannoma.
B. Soft tissue mass with blunting of the scutum and erosion of ossicles (correct)
Correct. Soft tissue with scutum blunting and ossicular erosion indicates cholesteatoma.
C. Fluid level in the cochlea
A cochlear fluid level is not a feature of cholesteatoma.
D. Enlarged vestibular aqueduct
An enlarged aqueduct is a congenital inner ear anomaly.
