Glomus tympanicum paraganglioma

Case contributed by Dr Bruno Di Muzio

Presentation

Long date progressive dizziness and hearing loss on the right.

Patient Data

Age: 55-year-old
Gender: Female
Modality: MRI

Tumour slightly high on T2 and FLAIR, with vivid contrast enhancement, partially obliterating the right middle ear, extending through the hypotympanum, surrounding the cochlear promontory until reaching the carotid canal. It contours and spares the cochlea. The mastoid adytum is obliterated causing mastoiditis on the right. 

Case Discussion

The imaging features are those of a glomus tympanicum paraganglioma, which is the most common tumour of the middle ear cavity. Unfortunately, this case was not confirmed histologically and this diagnosis is just supported by the radiological characteristics.
