Abstract：Objective To investigate clinical manifestations, imaging and pathological features, and differential diagnosis of glomus jugulare and glomus tympanicum tumor. Methods The imaging and pathological data of 1 case confirmed by surgery and pathology of glomus jugulare and glomus tympanicum tumor was retrospectively analyzed and the related literature was reviewed. Results CT scan showed a large soft tissue mass in the left jugular foramen, middle ear, tympanic antrum, and mastoid cells combined with local mastoid destruction and the lesion protruding into the left external auditory canal. Cranial MRI showed a irregular strip mass in the left jugular foramenm, grew along the outside of the left jugular foramen prominent cranial and extended into the left parapharyngeal space, convex to the left tympanic and mastoid. Immunohistochemistry staining were positive for Syn,NSE,CD56,CD34,CgA, negative for CK, the ki-67 proliferation activity was low (<1%), which indicate paraganglioma. Conclusion The bone destruction of jugular foramen and tympanicum, obvious enhancement of the lesion,rapidly wash in and wash out of the dynamic curve support the diagnosis of the glomus jugulare and glomus tympanicum tumor. It is helpful to outline the range of the tumor combing CT and MRI.
