case_images: Preoperative chest computed tomography (CT) scan demonstrated a homogenous, sharply-circumscribed mass in the left lower lobe (
  arrow
  ), and an aberrant feeder artery originating from the descending aorta (
  arrowhead
  ).

case_images: An aberrant feeder artery arose from the descending aorta into the lesion (Figure  1).
case_images: Intraoperative findings. A: A 2.5 cm skin incision was made, and a wound retraction system (Alexis Wound Retractor, Applied Medical, Rancho Santa Margarita, CA USA) was then placed through the incision. B: A pedunculated tumor was observed, which protruded into the thoracic cavity from the descending aorta. Sequestration lobe (asterisk), normal lung (arrow) and diaphragm (arrowhead). C: The aberrant artery was ligated and clipped.

case_images: Exploration through the left 7th intercostal space using a 5-mm trocar was performed, and a pedunculated tumor that protruded into the thoracic cavity from the descending aorta was observed (Figure  2B). Applied Medical, Rancho Santa Margarita, CA, USA) was then placed through the incision. A rigid 5-mm 30  video-thoracoscope, an endograsper and an electric cautery were passed within the same single small incision (Figure  2A). The tumor was suspended using articulating endograspers (Covidien, Norwalk, CT, USA) and resected after clipping and ligation of the anomalous vessel (Figure  2C).
