case_images: Computed tomography (CT) scans demonstrated a well-demarcated right-sided 5.5 x 2.6 cm paramediastinal solid mass, with associated atelectasis of the RUL (Figs 1 and 2). Traversing this segment, a large venous tributary of the azygous vein was identified (Fig. 2).
case_images: (A, B): Intraoperative thoracoscopic images demonstrating pulmonary sequestration (top arrow). A venous branch (middle punctuated arrow) of the azygous vein (middle solid arrow) may be appreciated. A surgical clip was placed on a systemic feeding artery (lowest arrow).
