case_images: Preoperative CT. Contrast CT showed the pure-solid nodule (diameter: 3.3 cm) in the left lingular segment (A), and PET-CT showed fluorodeoxyglucose uptake, with an SUV max of 3.7 for the same nodule (B).. PET, positron emission tomography

case_images: Contrast computed tomography (CT) showed a pure-solid nodule with spiculation and a size of 3.3 cm in diameter in the left lingular segment (Fig. 1A). Fluorodeoxyglucose positron emission tomography revealed abnormal accumulation in the nodule in the left upper lobe (Fig. 1B), and the nodule size remained unchanged.
case_images: Preoperative electrocardiogram. The electrocardiogram before surgery showed a Wolff-Parkinson-White pattern.

case_images: The electrocardiogram showed a Wolff-Parkinson-White pattern (Fig. 2), but he had never had any episodes of tachycardia.
case_images: Intraoperative findings. The pulmonary vein of the lingular segment is resected using a stapler (A), and the vein of the superior segment is resected separately (B).. Arrowhead (blue), pulmonary vein stump of the lingular segment; arrowhead (green), pulmonary vein stump of the superior segment.

case_images: The left lingular and superior segmental veins were dissected separately using a stapler (Fig. 3).
case_images: Thromboses on CT. Contrast CT immediately after the return of spontaneous circulation suggested thrombosis of the pulmonary vein stump. Arrowhead, pulmonary vein stump

case_images: After spontaneous circulation was secured, a contrast CT scan was performed, which showed that thrombosis of the pulmonary vein stump was highly suspected (Fig. 4).
case_images: Coronary angiography. Coronary angiography shows occlusion of the right coronary artery (arrowhead) (A). Most blood clots were removed by percutaneous coronary intervention, although some remained in the peripheral coronary artery (B). Follow-up coronary angiography before discharge shows no apparent stenosis in the coronary arteries (C).

case_images: Although some blood clots remained on the peripheral side of the RCA, treatment was completed with coronary flow improvement (Fig. 5B). No apparent stenosis was detected in the coronary arteries on follow-up coronary angiography before discharge (Fig. 5C).
