Tension pneumocephalus after surgical evacuation of chronic subdural hematoma: case report and pathophysiological mechanism

Introduction: Pneumocephalus is a frequent complication following neurosurgical procedures. The diagnosis is based on tomographic findings and the clinical evolution of the patient. Therefore, we detail the physiopathological mechanisms that trigger this complication. Clinical Case: We present the clinical case of an 85-year-old man who underwent a keyhole craniotomy and subdural drainage placement due to the diagnosis of a chronic subdural hematoma (CSDH) and subsequently developed sudden tension pneumocephalus which triggered the death of the patient due to intracranial hypertension. Conclusion: Tension pneumocephalus is a life-threatening complication that must be suspected early and must be treated as an emergency.
