A Decade-Old Retained Intrapleural Glass Fragment in an Asymptomatic Skydiver: A Case Report and Review of the Literature
This case report describes the rare discovery and successful surgical removal of a large, asymptomatic glass fragment retained in the pleural space for a decade in a skydiver, highlighting the challenges of detecting and managing such foreign bodies that may migrate years after the initial trauma.

The human body is remarkably resilient, often healing itself after severe injuries without leaving a trace. However, when a sharp object pierces the chest, it can sometimes slip past the body's natural defenses and remain hidden inside the rib cage. This is particularly true with glass, a material that is common in accidents but can be missed during initial assessments depending on its size and composition. Unlike metal, which shows up clearly on X-rays, glass can sometimes be overlooked if it is small or obscured by bone, though many fragments are radio-dense and visible on plain radiographs. When a piece of glass stays inside the chest cavity, it does not always cause immediate pain or trouble. Instead, it can sit quietly for years, surrounded by scar tissue, waiting to potentially cause problems later. Doctors generally agree that if a sharp, loose piece of glass is found inside the chest, it should be removed to prevent it from moving and damaging vital organs like the heart or lungs, even if the patient feels perfectly fine.
This story begins with a thirty-four-year-old skydiver who was living a completely normal, active life until a routine medical checkup revealed a mystery. During a standard chest X-ray taken for his skydiving license, a doctor noticed an unusual shadow on the right side of his chest. The man had no symptoms; he did not cough, feel pain, or have trouble breathing. He had been jumping out of airplanes for years without issue. However, when doctors asked him about his medical history, he recalled a frightening event from ten years prior. During a parachute landing, he had crashed through a window, sustaining a deep cut on his right side. At the time, he was treated for a collapsed lung filled with blood and air, a condition known as haemopneumothorax. A tube was inserted to drain the fluid and air, and after twelve days, it was removed. The doctors at that time focused on saving his life from the immediate trauma and never suspected that a piece of the broken window had been left inside him. He recovered, returned to skydiving, and remained symptom-free for a decade.
When the man arrived at the hospital for the new investigation, his physical exam showed signs of that old injury. His right side of the chest looked slightly smaller than the left, and the ribs were crowded together, suggesting that the lung had not fully expanded over the years. A detailed computerized scan, which creates a three-dimensional map of the inside of the body, confirmed the presence of a foreign object. It was a long, sharp piece of glass, measuring seven centimeters by two and a half centimeters. The scan showed that the glass was embedded deep within the lining of the chest cavity, surrounded by thick, dense scar tissue that had formed around it over the ten years. The object was not touching any major blood vessels or the heart, but its sharp edges and large size made it a significant risk if it were to shift position.
To remove the object, the medical team decided on a surgical approach. Because the glass was trapped in a web of tough scar tissue and the chest cavity had become stiff and contracted, a minimally invasive procedure using small cameras would likely be too difficult and risky. Instead, the surgeons performed an open operation, making an incision along the side of the chest to access the area directly. They carefully peeled away the dense adhesions that had grown around the glass over the decade. Once the scar tissue was cleared, they were able to pull out the glass fragment intact. The piece was exactly the size seen on the scans, a sharp shard that had been silently residing in his body for ten years. The surgery was successful, and the man recovered without complications. He was discharged ten days after the operation and, after a period of healing, returned to his passion for skydiving.
This case highlights a rare but important lesson in medicine. While most people remember the moment they are injured, and doctors usually find any foreign objects during the initial emergency treatment, this situation shows how a dangerous object can be missed entirely. The man's body had successfully walled off the glass with scar tissue, preventing it from causing pain or infection for a long time. However, the risk of the glass moving and causing a sudden, severe injury remained. The discovery of the glass was purely accidental, found only because the man underwent a routine checkup. It serves as a reminder that a history of chest trauma, even from many years ago, should never be ignored when unexplained shadows appear on an X-ray. For sharp objects like glass, the safest course of action is to remove them, even if the patient feels healthy, to prevent future disasters.
