Case Discussion

Right sided middle ear soft-tissue lesion near the cochlear promontory. This lesion enhanced on MRI (not shown) consistent with a glomus tympanicum paraganglioma, which is the most common tumour of the middle ear cavity. These tumours can be asymptomatic, produce conductive hearing loss through contact with the ossicles (as in this case), or result in pulsatile tinnitus. This mass was observed to be stable over many years without treatment.
