After the operation the chest x-ray showed a radiopaque filament at the retrocardiac region. This case report shows the serial radiological examinations by computed tomographic scans over 4 years demonstrating a well-defined mass adjacent to left ventricle with a radiopaque filament inside with pseudocystic changes in time. As far as we know this case is the first one in the literature showing the changes in a case of gossypiboma, as the patient refused surgery.eninfo:eu-repo/semantics/openAccessPericardium; Complications; Computed Tomography; X Ray; Medicolegal AspectsArticle427227410.4328/JCAM.2261WOS:000215553400018N/A
