CT and intracranial manifestations of otorhinologic disease.

Most inflammatory and neoplastic diseases of the ear, nose, nasopharynx, and paranasal sinuses have the capability of intracranial extension.

Trauma can simultaneously affect both intracranial and extracranial compartments but because of its scope, is not dealt with in this submission.
