The persistent otorrhea of chronic otitis media may be a predisposing factor. Radiation therapy and resection of the temporal bone are necessary. They produce a pulsatile red mass in the middle ear. The first symptom is often tinnitus that is synchronous with the pulse. Hearing loss develops, followed by vertigo.
Excision is the treatment of choice.
For tumors too large to excise, palliation is achieved with radiation therapy. All rights reserved.
