Suspected papillary fibroelastoma in a child: multimodality imaging and conservative management: a case report
This case report describes a 3-year-old girl with a suspected papillary fibroelastoma who was successfully managed conservatively with low-dose aspirin and close multimodality imaging follow-up over three years, suggesting that non-surgical management may be a viable option for asymptomatic children with small, stable, non-mobile intracardiac tumors.

The human heart is a relentless pump, but like any complex machine, it can develop unexpected growths. In children, these growths are rare, and most are benign, meaning they are not cancerous. However, even a harmless lump inside the heart can be dangerous if it breaks loose and travels through the bloodstream, potentially causing a stroke or blocking a valve. One such rare growth is called a papillary fibroelastoma. These are small, delicate tumors that often attach to heart valves, looking somewhat like a sea anemone with tiny, finger-like projections. Because they are so uncommon in children, doctors have very little data on how to handle them. The standard approach for many heart tumors is to remove them surgically, but surgery carries its own risks. This leaves medical teams with a difficult question: when a child has a small, silent tumor that isn't causing problems, is it safer to operate, or is it safer to watch and wait?
A team of researchers at a cardiac center in Tehran recently shared the story of a three-year-old girl who helped answer this question. The child was healthy and active until a routine checkup revealed a soft, unusual sound in her heart. Further investigation using ultrasound and advanced magnetic resonance imaging revealed a tiny mass, measuring just 5.7 by 3 millimeters, attached to the delicate cords that help the mitral valve close. The imaging showed the mass was solid and did not have its own blood supply, features that strongly suggested it was a papillary fibroelastoma. Crucially, the mass did not move when the heart beat, and the child had no symptoms of illness, chest pain, or fainting.
Instead of rushing to surgery, the medical team chose a path of careful observation. They started the girl on a low dose of aspirin, a common medication that helps prevent blood clots from forming on the surface of the tumor. For the next three years, they monitored her closely with regular heart scans and checkups. The results were reassuring. The tumor did not grow, it did not become mobile, and the child remained perfectly healthy with her heart pumping normally. After three years of stability, a group of specialists reviewed her case and agreed to continue this conservative approach, avoiding surgery entirely.
This case is significant because it challenges the assumption that every heart tumor in a child must be removed immediately. While surgery is often the go-to solution for mobile tumors or those causing symptoms, this report suggests that for a specific group of children—those with small, stationary tumors who feel fine—watchful waiting is a viable option. The researchers relied heavily on cardiac magnetic resonance imaging, a powerful tool that can look inside the tissue of the tumor to confirm its nature without needing a biopsy. By combining this detailed imaging with long-term monitoring, the team demonstrated that they could safely manage the condition without invasive procedures.
The study does not claim that all heart tumors can be treated this way, nor does it suggest that surgery is never necessary. The authors are careful to note that their conclusion is based on a single case and that more data is needed to fully understand the risks. However, the story of this young girl provides a concrete example that in the right circumstances, the most aggressive treatment is not always the best choice. It highlights a shift in thinking where the stability of the patient and the specific characteristics of the tumor guide the decision, offering a potential alternative to surgery for a select few who might otherwise face an unnecessary operation.
