These include erosion into the oesophagus [3, 4] with subsequent need for oesophageal stenting [5]; erosion into the pleural space with fibrin glue closure as a treatment option [6], erosion into the phrenic nerve with resulting palsy [7] and erosion into the thoracic duct causing chylothorax [8].

Bronchoscopy demonstrated a defect in the wall of the left lower lobe bro ...
