title: Massive cranial ossifying myxoma in a child.
abstract: A case is presented in which a myxoma developed in the mastoid region in the cranium and extending to the middle and posterior fossa. The patient was an 11-year-old girl with a history from birth of a painless mass in the mastoid region. On admission, she had bilateral papilledema, left homonymous hemianopia, and right hearing impairment. The computerized tomography showed a massive low-density area with intralesional ossification. The extra-axial mass was completely removed. Skepticism toward the existence of myxoma affecting the cranium, in an extragnathic osseous site, is discussed.
