Tumors of the temporal bone and skull base tend to arise in 1 of 3 locations: (1) the mastoid or middle ear, (2) the jugular foramen, or (3) the petroclival junction or petrous apex. Tumors of the cerebellopontine angle (CPA) and Meckel cave are not considered in this chapter (see Chapter 63, Acoustic Neuromas, and Chapter 64, Nonacoustic Lesions of the Cerebellopontine Angle). Tumors arising within the skull base are rare and usually cause few symptoms until they grow to a size in which they begin to affect cranial nerves. Table 67–1 lists the various skull base neoplasms and their imaging characteristics.
