case_images: (A) The triangle is a extralobar pulmonary sequestration, the five-pointed star is an esophageal duplication, and the quadrilateral is a bronchogenic cyst. (B) The triangle is the outer extralobar pulmonary sequestration, and the arrow is the abnormal artery of the outer extralobar pulmonary sequestration. (C) The triangle is the outer extralobar pulmonary sequestration, the pentagram is the esophageal duplication, the quadrilateral is the bronchogenic cyst, and the arrow is the abnormal artery of the outer extralobar pulmonary sequestration.

case_images: Contrast-enhanced computed tomography (CT) of the patient's chest revealed an abnormal density indicative of a solid sac in the lower lobe of the right lung (Figure 1A, triangle, pentagram, quadrangle) (Figure 1B, triangle, arrow). Thoracoscopic surgery was performed under general anesthesia, during which there was red, uninflated lung tissue measuring approximately 3 x 3 x 2 cm in the right mediastinum near the hilus of the lung on the farthest side (Figure 1C, triangle). Further exploration revealed a 2 x 2 x 1 cm cystic mass (Figure 1C, pentagram) and a 1.5 x 1 x 1 cm cystic mass in the intraoperative free surrounding tissue (Figure 1C, quadrangle). During thoracoscopic surgical separation, abnormal arterial supply vessels with a diameter of approximately 0.15 cm originating from the thoracic aorta were observed (Figure 1C, arrow).

case_images: Pathological findings revealed foliar isolation of the lung (lung histological results; Figure 2A). Esophagogenic cysts (the squamous epithelium of the digestive tract is seen inside; Figure 2B) and bronchogenic cysts (respiratory epithelium dominated by pseudostratified ciliated columnar epithelium; Figure 2C) were also observed.
