Coma Scale (GCS) scored 11/15 (E3, V4, M4), with vomiting and irritability. Computed tomography (CT) of the cranium revealed a huge intracranial aerocele, including lateral, third, and fourth ventricles extending to the cervical subarachnoid spaces [Figure 1].
Computed tomography scan of the head (sagittal view), 3-h postoperation shows reduced pneumocephalus intracranially.

The 3-h postoperative CT scan [Figure 2] showed progressive filling of the fourth ventricle, cisterns Magna, and the upper cervical subarachnoid spaces.
Cranial computed tomography scan (sagittal view), 8-h postoperation shows subsequent reduction of the pneumocephalus.
