Pneumolabyrinth as a late sequela of temporal bone fracture.
Pneumolabyrinth, air in the labyrinthine system, is an uncommon entity. We report one case, adding to previous reports of two such cases. The diagnosis was made radiologically, which has become possible only recently with the advent of high-resolution computed tomography (CT) scanners; we suspect it will be used more often in the future. To our knowledge, this is the first case in which pneumolabyrinth has been identified as a delayed sequela of a temporal bone fracture. Furthermore, this is the first description of a pneumolabyrinth occurring in a transverse temporal bone fracture.
