Extradural and epicranial pneumatocele is a rare condition. It may complicate with CSF rhinorrhoea and meningitis which can have a fatal outcome. We present a case of delayed post-operative extradural and epicranial pneumatocele in the frontal region following primary repair of the anterior skull base for a traumatic compound craniofacial injury with CSF leakage. There was no evidence of meningitis or raised ICP. As the patient was neurologically stable; he was managed conservatively and had a spontaneous resolution of the pneumatocele.
