Rare location and drainage pattern of right pulmonary veins and aberrant right upper lobe bronchial branch: A case report

Figure 1  Ground-glass nodule of right upper lobe in chest computed tomography.

Figure 2 Anatomic aberration of pulmonary vessels. A: Right upper lobe vein (RULV) lies behind right pulmonary artery (RPA) in thin-section computed tomography (CT); 2B: Right middle lobe vein joins right lower lobe vein to form one common trunk vein drained into left atrium in thin-section CT; C: RULV lies behind right pulmonary artery under thoracoscope; D: Three-dimensional reconstruction of pulmonary vessels.

Figure 3 Abnormal right preeparterial bronchus. A: Right preeparterial bronchus arose from right main bronchus alone in thin-section computed tomography; B: B²⁺³ arose below right preeparterial bronchus from right main bronchus; C: Right preeparterial bronchus and B²⁺³ under thoracoscope; D: Stump of right preeparterial bronchus after stapling and B²⁺³ under thoracoscope; E: Three-dimensional reconstruction of trachea and bronchus.
