Pneumolabyrinth: an unusual finding in a temporal bone fracture.

Pneumolabyrinth or pneumocochlea are rarely found in temporal bone fractures. The presence of air in the inner ear is evidence of a pathological connection between the inner ear and the air-filled mastoid or middle ear cavities. A case of a pneumolabyrinth in a 2-years-old child is presented here. Diagnosis was made by means of a high resolution, thin sections computed tomography (CT) scan of the temporal bones, which is the imaging modality of choice in cases of otologic complaints after head trauma.
