Floating thrombus in the right atrium (RA) is an uncommon but severe condition that can cause significant complications such as pulmonary embolism (PE) and systemic embolism. Its detection in cancer patients presents diagnostic challenges due to the overlapping symptoms of thromboembolic events and malignancy. This article presents a case of floating thrombus in the right atrium in a 50-year-old male patient diagnosed with advanced non-small cell lung cancer (NSCLC), who developed this condition following a pulmonary embolism (PE). The article also reviews the pathophysiology, clinical manifestations, diagnostic techniques, and management strategies for floating thrombus in cancer patients, particularly those with NSCLC. Early diagnosis and treatment are vital to avoid life-threatening complications and improve patient outcomes.
