Bilateral Cerebellopontine Angle Osteomas: Case Report and Review of the Literature
Osteomas and exostoses of cerebellopontine angle (CPA) are very rare, benign, and usually slow-growing lesions; few case reports have been published about these lesions in literature. The most common localizations of these temporal bone lesions are the mastoid cortex and the external acoustic canal....

description | Osteomas and exostoses of cerebellopontine angle (CPA) are very rare, benign, and usually slow-growing lesions; few case reports have been published about these lesions in literature. The most common localizations of these temporal bone lesions are the mastoid cortex and the external acoustic canal. To our knowledge, only two cases of bilateral osteoma arising from both internal acoustic canals (IACs) have been reported. However, these tumors are usually asymptomatic and diagnose incidentally, and they can cause symptoms related to the 7(th) and 8(th) cranial nerve involvement. We report on a 75-year-old woman affected with bilateral osteoma of CPA and review the literature that 27 cases of IAC osteoma and exostoses have been reported. |
