Pneumorrhachis as a relatively rare condition may be an indication of substantial intra-spinal column injury. Here we report a 39-year-old man was admitted because of low back pain and dyspenea after locating between motor vehicle and wall three days before admission. On arrival, physical exams and vital signs were normal. Computed tomography (CT) scan showed bilateral pleural effusion, fracture of ribs number 8, 9 and 10 in lower left side of thorax, fracture of vertebra in L2-L4, and air bubbles in upper thoracic spinal canal.
