Pulmonary arterial aneurysm (PAA) is a rare condition involving a focal dilation of the pulmonary artery and all three layers of the vessel wall. Few reports have described managing this anomaly using video-assisted thoracoscopic surgery (VATS). Here, we report a 60-year-old woman with a PAA in the truncus superior of the right pulmonary artery. The patient underwent a two-port VATS with a right upper lobectomy. The postoperative course was uneventful. She maintained a good prognosis for 4 months after surgery, and we continue to take great care throughout her follow-up.
