RESUMO
A pneumatocele is an air-filled cavity in the body. In the head and neck areas, the extensive hyperpneumatization of the temporal and occipital bones is typically associated with pneumatocele formation, which results in the spontaneous collection of gas, usually air, beneath the pericranium or within the skull. We herein report a case of stenosis of the external auditory canal caused by a left mastoid pneumatocele in a 12-year-old boy who was successfully treated with left simple mastoidectomy and canaloplasty.

The majority of cases of pneumocephalus are secondary to trauma or medical intervention. Spontaneous, non-traumatic pneumocephalus is an uncommon condition. Most cases of spontaneous pneumocephalus require surgery. However, if there is no evidence of infection or cerebrospinal fluid leak, bed rest and follow-up imaging is an alternative treatment. Herein, we report a 31-year-old man with spontaneous pneumocephalus associated with pneumosinus dilatans.
