Lung adenocarcinoma with anomalous bronchi and pulmonary veins preoperatively identified by computed tomography

A 69-year-old woman visited our hospital complaining of right chest pain. Chest computed tomography showed a 55 × 45 mm tumor in the right upper lobe. Bronchoscopy revealed displaced anomalous B ¹ and B ²⁺³ arising from the right main bronchus, and the patient was diagnosed with lung adenocarcinoma by transbronchial lung biopsy from the displaced B ²⁺³ . Three-dimensional computed tomography with multiplanar reconstruction revealed a displaced anomalous B ¹ and B ²⁺³ branching directly from the right main bronchus, respectively, and abnormal distribution of the aberrant pulmonary vein (V ² ) descended dorsally to the right main bronchus and emptied into the left atrium. Video-assisted right upper lobectomy with nodal dissection was successfully performed. Attention should be paid to the anomalous bronchus and pulmonary vessels for safer lung cancer operations, especially for video-assisted thoracic surgery.
