Diagnosis and treatment of gastric bronchogenic cyst: a case report and literature review
This case report describes the successful laparoscopic resection and histopathological confirmation of a rare gastric bronchogenic cyst in an asymptomatic woman, highlighting the diagnostic challenges in distinguishing it from other submucosal lesions like GISTs and underscoring the efficacy of minimally invasive surgery for curative treatment.

Inside the human body, the journey from the throat to the stomach is a straight, muscular tube that usually ends at a simple, one-way valve. But in the earliest days of life, before a baby is born, the tissues that form this tube and the lungs are still learning to separate. Sometimes, a tiny piece of tissue meant to become part of the airway gets left behind or wanders off course, settling in the wrong place. When this happens near the stomach, it can form a hidden pocket of fluid called a bronchogenic cyst. These are rare, benign growths that do not usually cause pain, often hiding quietly until a doctor finds them by accident while looking for something else. Because they sit deep inside the abdomen and look like other common lumps on medical scans, doctors often struggle to know exactly what they are before surgery, leading to a difficult puzzle of diagnosis and treatment.
This story begins with a forty-two-year-old woman who felt perfectly fine. She had no pain, no nausea, and no trouble eating. During a routine checkup, a doctor noticed a small, fluid-filled lump near the top of her stomach, right where the esophagus meets the stomach. To understand what this lump was, the medical team used powerful cameras and scanners. A special type of X-ray called a CT scan showed a smooth, round mass about the size of a large grape, measuring three centimeters by two centimeters. When they injected a dye to see how blood flowed through it, the mass did not light up, suggesting it was not a tumor made of blood vessels. An MRI scan confirmed the picture, showing the lump was filled with fluid and had a clear, smooth edge. A camera passed down her throat showed the inside of her stomach was smooth, with just a small bump pushing outward from the wall. Despite these clues, the doctors could not be certain if this was a harmless cyst, a type of tumor that often forms in the stomach, or a different kind of growth. Because they could not tell for sure without looking inside, and because the lump could grow or cause problems later, they decided to remove it.
The surgery was performed using a minimally invasive approach, where the surgeon made several tiny cuts in the abdomen and used a camera and long instruments to work inside. The team carefully located the mass, which was attached to the top part of the stomach. The most important part of the operation was to peel the lump away without breaking it open, because spilling its contents could cause infection or irritation inside the belly. The surgeon gently separated the cyst from the stomach wall, preserving the muscle layer of the stomach so it would remain strong and functional. Once the mass was free, the small opening in the stomach muscle was stitched back together securely. The entire procedure was completed successfully, and the patient recovered quickly, returning to her normal life within a week.
When the removed mass was examined under a microscope, the mystery was finally solved. The outer wall of the cyst was lined with a specific type of tissue that normally only exists in the airways of the lungs, covered in tiny, hair-like structures that help move mucus. This unique lining confirmed that the lump was indeed a bronchogenic cyst, a rare piece of lung tissue that had ended up in the stomach. The patient had no complications from the surgery and was checked again three months later, showing no signs that the lump had returned. This case highlights that even when a medical scan shows a clear, fluid-filled lump that does not behave like a typical cancer, doctors must consider rare possibilities like this. It also demonstrates that removing such a lump with a careful, minimally invasive technique is a safe and effective way to both identify the problem and cure it, leaving the patient healthy and the diagnosis confirmed.
