This female patient in her early 70s had a 2cm apical left upper lobe tumour with a 17mm FDG avid lymph node on the superior aspect of the lung hilum. It was unclear if this represented a station 10 or 5 lymph node. Regardless, the lung multidisciplinary meeting recommended she undergo surgical resection. At surgery the node in question was clearly a AP window (station 5) node. In addition, she had a mediastinal lingular artery, which is said to be present in up to 20% of patients. Her lung fissure was nearly absent. The patient was discharged from hospital on post-operative day 5 as she had a small air leak for the first 3 days.
