Tracheocele: a rare life-threatening condition in pediatric surgery – A case report
This case report describes a rare instance of a life-threatening tracheocele with microperforation in a 5-year-old girl following a Sistrunk procedure, which was successfully managed through conservative treatment leading to spontaneous resolution.

The human windpipe, or trachea, is a sturdy tube that carries air to the lungs, reinforced by rings of cartilage that keep it open while a flexible, muscular back wall allows it to expand and contract during swallowing. Usually, this structure is seamless, but in rare instances, a weak spot can develop in that back wall. When pressure builds inside the airway, the soft inner lining can push through this defect, forming a pouch. This condition, known as a tracheocele, is so uncommon in children that doctors often do not know how to handle it when it suddenly causes trouble. Because the condition is hidden and unpredictable, a child with no prior health issues can appear perfectly healthy one moment and face a life-threatening emergency the next, leaving medical teams to race against time to understand what has gone wrong and how to fix it without causing further harm.
In a recent report from a children's hospital in Italy, a team of surgeons and anesthesiologists described just such a startling event involving a five-year-old girl. The child had been admitted for a routine, elective surgery to remove a cyst from her neck, a procedure that typically carries very low risk. She was healthy, had no history of breathing problems, and showed no signs of any airway abnormalities before the operation began. However, immediately after the surgery, while she was still under the effects of anesthesia and had just been woken up, she began to struggle for air. Her neck and upper chest rapidly filled with air trapped under the skin, a condition called subcutaneous emphysema, which made her look puffy and caused her severe distress. X-rays taken at the scene revealed that air had escaped her lungs and was filling the space around them on both sides, a situation known as a pneumothorax, as well as the middle of her chest.
The medical team acted quickly to stabilize the child. They placed a tube down her throat to secure her airway and inserted a drainage tube into her chest to let the trapped air escape, allowing her lungs to reinflate. They also used small needles to release the air trapped under the skin of her neck. Once her breathing stabilized, the doctors used a specialized camera to look inside her windpipe. This examination revealed the source of the crisis: a large pouch, about three centimeters long, had formed on the back wall of her trachea. This pouch, the tracheocele, had a tiny hole at its base where air was leaking out. The doctors realized that the pressure from the breathing tube used during her surgery had likely forced air through this weak spot, causing the pouch to inflate and eventually rupture, leading to the dangerous air leaks that had threatened her life.
Despite the severity of the situation, the team decided against immediate surgery to repair the hole. Instead, they chose a careful, conservative approach. They kept the child in the intensive care unit, monitored her closely, and treated her with antibiotics to prevent infection. Over the next few days, her condition slowly improved. The air leaks stopped, her lungs stayed inflated, and the swelling in her neck went down. After eight days, she was able to breathe on her own without the breathing tube, and she was moved to a regular hospital ward. She was discharged eighteen days after the surgery in good health. When the doctors looked inside her windpipe again one month later, the large pouch had shrunk significantly on its own, leaving only a small, harmless remnant.
This case highlights a critical lesson for medical professionals: even in a child with a clean bill of health, a hidden weakness in the windpipe can turn a routine surgery into a crisis. The report suggests that while tracheoceles are rare, they should be considered when a patient develops sudden, severe air leaks after intubation. The authors emphasize that recognizing the problem early and managing the complications, such as draining the air and securing the airway, can save a life. Furthermore, the outcome of this specific case suggests that in some children, the body can heal these defects on its own without the need for invasive surgery, offering a hopeful path forward for similar patients in the future.
