Case Series: Pericardial gossypibomas detected after cardiovascular surgery: Imaging findings
A 36-year-old male patient who had undergone aortic valve replacement operation 18 months earlier was admitted to our hospital with the complaint of discharge at the low end of the sternotomy site. Chest radiograph showed a radiopaque marker on the superior vena cava–right atrium junction. An enhanced chest CT demonstrated well-defined right-sided intrapericardial mass lesion near the aortic valve, which opened to the subxiphoid region with a fistula tract and also contained infolded linear dense sponge markers [Figures and ]. The patient underwent a second operation and a sponge was removed [].
