Results: The report outlines the case of a 7 year old male patient who presented to emergency department in semiconscious state with blood stained discharge from the left ear. High resolution computed tomography revealed left sided pneumolabyrinth involving vestibule and cochlea with capsule violating transverse fracture of left temporal bone. Patient was managed conservatively. Conclusion: Pneumolabyrinth following temporal bone fracture is an extremely rare condition. Visualization of air in vestibule, cochlea or semi-circular canals should prompt careful evaluation of petrous temporal bone and inner ear structures to look for fractures and associated complications.
