Retained foreign body in ethmoid with bilateral pneumoencephaly.

Intracranial penetrating injury through the nose is rare. We present a case of a 79 year-old patient who had intracranial penetrating injury with a wooden object accompanied by massive bilateral pneumoencephaly with the presence of a foreign body in the ethmoid bone with fracture and displacement of crista galli. This is a hitherto unreported retained foreign body with fractured ethmoid resulting in bilateral pneumoencephaly.
