Tension pneumocephalus is a rare complication of head trauma and neurosurgical procedures, amongst other causes. It is defined by the combination of intracranial air, increased intracranial pressure, and mass effect. Although it often presents soon after surgery, it can also rarely present in a delayed fashion. We present a case of delayed tension pneumocephalus, occurring approximately 16 weeks after bifrontal craniectomy for a self-inflicted gunshot wound. Following a month of rhinorrhea, postnasal drip, and cough, the patient presented with a sensation of expansion in the area of the right forehead. As tension pneumocephalus is an emergency that can be fatal, this patient was treated expediently and avoided severe neurological deficits. The case recounted here is important as a demonstrative example that tension pneumocephalus does not always follow a defined course immediately after trauma or neurosurgery but rather can develop insidiously without obvious signs.

Pneumocephalus is commonly seen after craniofacial injury. The pathogenesis of pneumocephalus has been debated as to whether it was caused by ball valve effect or combined episodic increased pressure within the nasopharynx on coughing. Discontinuous exchange of air and cerebrospinal fluid due to "inverted bottle" effect is assumed to be the cause of it. Delayed tension pneumocephalus is not common, but it requires an active management in order to prevent serious complication. We represent a clinical case of a 57-year-old male patient who fell down from 3 m height, complicated by tension pneumocephalus on 5 months after trauma. We recommend a surgical intervention, but the patient did not want that so we observe the patient. The patient was underwent seizure and meningitis after 7 months after trauma, he came on emergency room on stupor mentality. Tension pneumocephalus may result in a neurologic disturbance due to continued air entrainment and it significantly the likelihood of intracranial infection caused by continued open channel. Tension pneumocephalus threat a life, so need a neurosurgical emergency surgical intervention.
