In the event of a car crash, airbags can be a lifesaver. However, airbags can sometimes explode when deployed and send shrapnel into the drivers and passengers, causing injury or death. Here we report a patient struck by shrapnel from an exploding airbag. The penetrating fragment damaged the T1 paravertebral area, leading to the Brown-Sequard syndrome and left subclavian artery disruption. After emergent operation for foreign-body removal and aggressive rehabilitation for 6 months, the patient recovered from motor and sensory loss almost completely.
