Case Discussion
Typical appearances of tympanic paraganglioma, the most common benign primary tumours of the middle ear. On a CT scan, the tumour may be visualised as a soft tissue mass within the middle ear cavity.
It was a preoperative CT scan for middle ear tumour. Unfortunately further clinical or imaging follow-up is not available for this case at this time.
