====== Pneumocephalus Classification ======

The accumulation of intracranial air can be acute (<72 h) or delayed (≥72 h)
((Solomiichuk VO, Lebed VO, Drizhdov KI. Posttraumatic delayed subdural tension pneumocephalus. Surg Neurol Int. 2013;4:37.))

Others classified it as early (<7 days) or late PNC (≥7 days)
((Ruiz-Juretschke F, Mateo-Sierra O, Iza-Vallejo B, Carrillo-Yagüe R. Intraventricular tension pneumocephalus after transsphenoidal surgery: A case report and literature review. Neurocirugia (Astur) 2007;18:134–7.)).

It can be located in the epidural, subarachnoid, intraventricular, intracerebral, or subdural space, with the subdural space most frequent. The common site is frontal, followed by the occipital and temporal areas
((Solomiichuk VO, Lebed VO, Drizhdov KI. Posttraumatic delayed subdural tension pneumocephalus. Surg Neurol Int. 2013;4:37.)).
