Glomus jugulotympanicum paraganglioma
Glomus jugulotympanicum paraganglioma is a glomus jugulare paraganglioma that has spread superiorly to involve the middle ear cavity. The term can also be used clinically when a suspected glomus tympanicum paraganglioma involves the hypotympanum as its inferior extent cannot be established clinically .
Practical points
As glomus tympanicum paraganglioma usually does not erode the floor of the middle ear, glomus jugulotympanicum paraganglioma should be the main consideration under these circumstances .
