Within the lungs there is patchy ground glass opacification within the right apex, left upper lobe anterior basal segment and right perihilar distribution with some very small foci of associated consolidation. The largest focus of opacity resides within the right apical lung and is in a reversed halo/atoll configuration.
No cavitation. No pleural or pericardial effusion. No axillary or mediastinal lymph node enlargement. Incidental note of variant aortic arch anatomy, with an aberrant retro-oesophageal right subclavian artery. No suspicious bony abnormality seen.
There is apparent severe stenosis or occlusion of the right subclavian vein with extensive shoulder girdle and chest wall collaterals diverging flow to the superior vena cava.
