Sonic pressure wave should be taken into consideration in all ballistic injury. We review a young gentleman with ballistic injury of his lateral chest wall. The bullet trajectory passed through the lateral chest wall. Chest radiograph shows a wedge-shaped consolidation adjacent to the wound with blunted right costophrenic angle. Subsequent CT scan confirms the consolidation adjacent to the bullet trajectory. This case report emphasizes on value of CT in ballistic chest trauma and indirect injury caused by the sonic pressure wave of the bullet.
