Bottom Line: The CT and dynamic MRI demonstrated an extensive tumor close to the carotid artery canal and the jugular bulb, and the tumor was removed by a partial petrosectomy with a transmastoid approach.The histopathological findings revealed a solid and trabecular tumor with cells positive for cytokeratin, chromogranin A, synaptophysin, and CD56.The relevant literature is reviewed in regard to the present case.

ABSTRACT
We herein report a 59-year-old male patient with a recurrent carcinoid tumor of the middle ear 7 years after a tympanomastoidectomy. The CT and dynamic MRI demonstrated an extensive tumor close to the carotid artery canal and the jugular bulb, and the tumor was removed by a partial petrosectomy with a transmastoid approach. The histopathological findings revealed a solid and trabecular tumor with cells positive for cytokeratin, chromogranin A, synaptophysin, and CD56. The MIB-1 antibody for the Ki-67 antigen was positive in 6.6% of the tumor cells. The relevant literature is reviewed in regard to the present case.

CT. The tympanum and mastoid were filled with an isodensity shadow with bone erosion. The wall of the carotid artery and jugular bulb appeared to be thick and erosive.  CA: carotid artery, JB: jugular bulb, TMJ: temporomandibular joint, EAC: external auditory canal, VII: the seventh nerve, PP: Petrous pyramid.

fig1: CT. The tympanum and mastoid were filled with an isodensity shadow with bone erosion. The wall of the carotid artery and jugular bulb appeared to be thick and erosive. CA: carotid artery, JB: jugular bulb, TMJ: temporomandibular joint, EAC: external auditory canal, VII: the seventh nerve, PP: Petrous pyramid.

Mentions: A 59-year-old male patient presented with ear pain and bleeding of the left ear, and upon closer investigation a reddish bulging mass extending through the left tympanic membrane from the middle ear was observed. The pure tone audiogram showed an 80-dB mixed hearing loss with an increased threshold of bone conduction in the high tone frequency range. The patient experienced no dizziness or facial palsy. The tympanum and mastoid were filled with an isodensity shadow indicating bone erosion, and the wall of the carotid artery canal and the jugular bulb appeared to be thick and erosive on CT (Figure 1). The mass was close to the carotid artery and jugular bulb through the tympanum, and the mastoid space was enhanced in the early and late phases of the dynamic MRI. The enhanced mass also appeared on the underside of the promontory of the middle ear (Figure 2). The patient had experienced a tympanomastoidectomy for tumors in the tympanum 7 years previously and the pathological diagnosis was adenoma of the middle ear.
