During any surgical procedure, complications may arise, some of which are fortuitous, whereas others, unfortunately, occur because of errors of the surgical team. Fortunately, most are minor and do not affect the patient's recovery, but others can cause severe morbidity and even mortality. A retained cotton or gauze surgical sponge inadvertently left in the body during an operation is known as a gossypiboma. This dreadful oversight is a marked complication that can cause serious postoperative complications, a severe economic burden on the healthcare system, and many medicolegal implications. We report the case of a 30-year-old male, who suffered a spinal fracture which was repaired through an anterior fixation approach 12 years ago in a local state hospital without complications. Suddenly, he presented with chest pain and cough, and sought medical attention. An 8 × 5 × 8 cm low-density heterogeneous mass was discovered on his chest; after successful surgery, a gossypiboma formed by several gauzes without radiopaque markers was discovered.
