Barosinus pneumocele: transient visual loss due to sphenoid sinus pneumocele in a U.S. Air Force pilot.
Symptomatic sphenoid sinus pneumoceles are extremely rare. This case presented in a U.S. Air Force aviator who had recurrent left-sided visual loss during ascent in jet aircraft. Computed tomography showed a dehiscent optic nerve within the left sphenoid sinus. Surgical correction included removing a mucosal polyp from the sinus ostium. The aviator has since flown 70 sorties without recurrence of symptoms. This entity is named barosinus pneumocele.
