detection of a gossypiboma as a retrocardiac mass in a female patient with a history of coronary artery bypass graft

Introduction: gossypiboma, also known as textiloma, refers to retained surgical items left in the body after an operation. these retained items can lead to a range of issues, from asymptomatic cases to life-threatening complications. diagnostically challenging, gossypibomas can mimic malignant masses, making it essential to consider them in the differential diagnosis of postoperative patients with unexplained symptoms. imaging is crucial for detection and management. case presentation: a 69-year-old female with a history of coronary artery bypass graft (cabg) surgery presented with exertional shortness of breath. imaging revealed a large mass near the left atrium. initially suspected to be a tumor, further investigation identified it as retained surgical gauze from her surgery ten years prior. despite the mass, the patient exhibited only mild symptoms, and given her stable condition, regular follow-ups were recommended. conclusions: gossypibomas are rare but serious complications that may surface years after surgery. this case highlights the importance of meticulous surgical practices and careful postoperative monitoring. it underscores the need for accurate gauze counting and effective communication in the operating room to prevent errors that can lead to health risks and potential legal issues.
