Successful pulmonary thrombectomy for malignant tumor thrombus after adrenal cancer resection

A 28-year-old patient presented with a right adrenal mass compressing the right kidney and invading the inferior vena cava. The tumor was completely resected; however, on a transesophageal echocardiogram intraoperatively, a new pulmonary artery thrombus, measuring 1.4 × 1.8 cm, was detected. The patient was therefore taken to the operating room the next day. The thrombus was visualized and removed and measured 4 × 2 × 1 × 1 cm. The pathology report identified the mass as an adrenal tumor thrombus with malignant elements. To our knowledge, this is the first known case report of an adrenal tumor thrombus successfully resected at the level of the left pulmonary artery.
