Findings of CT and 3D reconstruction in a patient with angioleiomyoma of the pulmonary artery. Contrast-enhanced computed tomography (CT) of the chest showed a well-demarcated mass with a maximum diameter of 1.7 cm in the right anterior basilar segment of the lung (RS8), adjacent to the basal branch of the right anterior basilar bronchus (RB8b). The lesion, displaying soft tissue density in the periphery, was penetrated by the basal branch of the right anterior basilar artery (RA8b) and bypassed by the lateral branch of the right anterior basilar vein (RV8a). Preoperative 3-dimensional (3D) reconstruction of the pulmonary vessels and bronchial trees of the right lower lobe from CT images was performed, and single-port RS8 segmentectomy was performed for histologic confirmation of the mass
