Both pathologies are extremely rare with relation to the mastoid. This paper describes a case of a mastoid pneumocele that caused hypoglossal nerve palsy and an intracranial pneumatocele.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215116009816_sec_a2\"><jats:title>Case report:<\/jats:title><jats:p>A 46-year-old man presented, following minor head trauma, with hypoglossal nerve palsy secondary to a fracture through the hypoglossal canal. The fracture occurred as a result of a diffuse temporal bone pneumocele involving bone on both sides of the hypoglossal canal. Further slow expansion of the mastoid pneumocele led to a secondary middle fossa pneumatocele. The patient refused treatment and so has been managed conservatively for more than five years, and he remains well.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215116009816_sec_a3\"><jats:title>Conclusion:<\/jats:title><jats:p>While most patients with otogenic pneumatoceles have presented acutely in extremis secondary to tension pneumocephalus, our patient has remained largely asymptomatic.
