👉The chest X-ray shows increased density in the upper medial hemithorax with a loss of volume and a shift of the trachea to the right.
👉A mass is present at the right hilum. The right hilar mass (orange) obstructing the right upper lobe bronchus results in the collapse of the right upper lobe (green arrow).
👉This results in a reverse S shape to the pleural edge: the Golden S sign.
The Golden S sign also 👉resembles a reverse S shape on posteroanterior (PA) chest radiographs and therefore may also be referred to as the reverse S sign of Golden.
👉The Golden S sign can be seen with the collapse of all lobes of the lung but is most commonly seen in right upper lobe collapse.
✨ It is created by a central mass obstructing the upper lobe bronchus and should raise suspicion of a primary bronchogenic carcinoma, of which about 80% are non-small-cell lung carcinomas
These include squamous cell carcinomas, which account for 30% of lung cancers and typically occur centrally
