Golden S sign is seen in:: (A) Bronchogenic carcinoma with collapse of lung, (B) Traction Bronchiectasis with apical scarring, (C) Emphysema with increased lucency and flattened diagphragm, (D) Pulmonary edema
Answer is A. Ans. (a) Bronchogenic carcinoma with collapse of lung* The Golden S sign (reverse S sign of Golden.) is seen in PA chest radiographs with right upper lobe collapse.* It is caused by a central mass obstructing the upper lobe bronchus and should raise suspicion of a primary bronchogenic carcinoma.* The right upper lobe appears dense and shifts medially and upwards with a central mass expanding the hilum. The combination of two changes together form a reverse S shane.
