Pneumocephalus is seen in conjunction with a variety of conditions, particularly traumatic injury, neurosurgical, and ears, nose, and throat (ENT) procedures. We describe the successful, non-operative management with supplemental oxygen of symptomatic pneumocephalus following polypectomy without further complication. This case adds to other case reports of pneumocephalus but differs in the non-invasive, conservative management with supplemental oxygen obviating the need for more invasive neurosurgical intervention such as decompressive craniectomy, burr holes, or drain placement
