4. Why does this sign occur? First described in right upper lobe collapse usually due to a proximal mass. The minor fissure is displaced superiorly and is concave peripherally but convex centrally, and the shape of the fissure resembles an S or a reverse S .

5. It can be seen in other lobes as well.

6. What does the sign signify? PRIMARY BRONCHIAL CARCINOMA should be suspected in any adult patient with golden S sign. Other causes: • P rimary mediastinal tumour . • Metastasis • E nlarged lymph nodes The sign may be useful for distinguishing a central obstructing mass from a consolidative process such as bacterial pneumonia.
