Small cell lung cancer:Station 1 (green) :This node is lying betweenthe left common carotidartery and the leftsubclavian arteryStation 3A (pink) :This is anterior to and leftof major arterial vessels

Small cell lung cancer and superior venacava syndrome:Station 2 (purple) :Note reflux into anteriorchest wall collaterals(curved arrows) and bothinternal mammary veins(straight arrows).

Small cell lung carcinoma and superiorvena cava syndrome:Station 4 (orange) :The inferior nodes arebelow a horizontal linedrawn at the superioraspect of the azygos vein.

Small cell lung carcinoma and superiorvena cava syndrome:Station 7 (blue) : SubcarinaladenopathyStation 8 (tan) : Theparaesophageal nodes lieposterolateral to theesophagus (white arrow)between azygos vein (blackarrow) and aortaStation 10 (yellow) : Hilar nodes

Small cell lung carcinoma:Station 13 :The segmental nodes are seen anterior tothe lateral basal bronchus.

Small cell lung carcinoma:Station 14 :The subsegmental node is seenadjacent to the subsegmentalbronchus (curved arrow). Theground glass opacity (blackarrow) represents the top of theprimary tumour.
