Summary
Cone beam computed tomography (CBCT) effectively identifies osseous changes in feline inflammatory aural polyps (IPs). This imaging modality reveals common changes like bulla thickening and auditory tube widening, aiding diagnosis.
Area of Science:
- Veterinary Radiology
- Comparative Imaging
- Feline Medicine
Background:
- Computed tomography (CT) is established for evaluating feline inflammatory polyps (IPs).
- Limited veterinary literature exists on cone beam CT (CBCT) for osseous changes in feline IPs.
- Osseous changes in the middle and inner ear are associated with IPs.
Purpose of the Study:
- Evaluate CBCT utility in identifying middle and inner ear osseous changes in cats with IPs.
- Determine the frequency of these osseous changes in young cats with IPs.
Main Methods:
- Retrospective review of 38 feline medical records with diagnosed IPs.
- CBCT bone window studies performed at 0.3-mm isotropic slice thickness without contrast.
- Evaluation by a board-certified veterinary radiologist.
Main Results:
- CBCT adequately visualized middle and inner ear structures in cats.
- Most frequent osseous changes: bulla thickening (65.7%), auditory tube widening (52.6%).
- Cochlear and ossicular chain lysis occurred in 7.8% of cases.
Conclusions:
- CBCT is a valuable initial diagnostic tool for suspected feline IPs.
- Osseous changes like bulla thickening and auditory tube widening on CBCT may indicate IPs.
- CBCT aids in diagnosing inflammatory aural polyps in cats.
