IntroductionLumbar epidural anaesthesia is a commonly used technique for analgesia during labour. One of the rare complications of this technique is pneumocephalus.Case DescriptionWe report the case of a 35-year-old female admitted to the Emergency Department with severe headache associated with fast head movements. Five days previously she had a eutocic delivery and lumbar epidural anaesthesia was performed. A brain computed tomography (CT) scan showed pneumocephalus and she was admitted to the hospital ward. A brain CT scan on the fourth day of hospitalization showed resolution of ventricular pneumocephalus.DiscussionThe most frequently occurring symptom with pneumocephalus is headache associated with fast brain motion resulting from air injection and meningeal irritation. When there is clinical suspicion of pneumocephalus, a brain CT scan should be performed for the diagnosis.Learning PointsPneumocephalus is the presence of air in the intracranial cavity and its development after spinal or epidural anaesthesia is extremely infrequent.Headache that occurs in the setting of lumbar epidural anaesthesia should not be labelled as post-dural puncture headache.The suspicion of pneumocephalus, based on the characteristics of the headache, should be maintained to obtain an emergent brain CT scan.© EFIM 2020.
