The "temporocele"

This article reports a case of spontaneous extracranial pneumatocele and introduces a new simple terminology for this clinical entity. A 10-year-old Saudi girl presented with left tympanoparietomastoid swelling. It was found to be fluctuant and full of air. On exploration, bony septae were found arising from the skull aponeurosis, the cranial boundary was elevated, and an ivory, cancellous bony swelling was over the root of the zygoma. No naked eye anatomic communication to the mastoid air cell was found. The mastoid pneumatization was within normal limits. All preoperative, operative, and postoperative investigations are presented. The authors introduce temporocele as a new term applied to this extracranial spontaneous pneumatocele.
