Symptomatic intracranial pneumatocele from mastoid sinus of spontaneous origin

Abstract

A case of a large intracranial pneumatocele arising from mastoid air cells is reported. The patient became symptomatic after multiple coughing spells and required craniotomy for repair of the dural hiatus. The possible etiology of such a large spontaneous pneumatocele is discussed in the context of a review of the pertinent literature.
