Enlarged vestibular aqueduct (EVA) is a malformation in the inner ear and occurs in approximately 1-12% of the hearing-impaired individuals. A ten-year-old girl was seen at the emergency room (ER) because of sudden hearing loss on the right ear. The patient was known with sudden deafness on the left ear. In the ER she appeared completely deaf. A head CT-scan showed EVA, and she was treated with cochlear implant. This case report illustrates the importance of performing MR- or CT-scan, especially when diagnosing children with sudden hearing loss after a head injury.
