A 65-year-old female non-smoker had a 3-month history of productive cough and intermittent haemoptysis for 1 month. Plain chest radiography showed a mass-like shadow at the medial side of the left lower lung field (fig 1A). A CT scan showed a left lower lobe mass with heterogeneous content neighbouring the left pulmonary artery and descending thoracic aorta, with encasement of the superior and basal posterior segments of the bronchi (fig 1B). A CT scan with contrast medium revealed a highly suspicious feeding artery arising from the descending aorta (fig 1C). Bronchoscopy demonstrated narrowing of the orifice of left B6 and B10 but sputum and washing/brushing cytology were all negative. The CT-guided biopsy specimen had few atypical cells, but a repeat ultrasound-guided biopsy specimen showed chronic inflammation.
