OCCLUDED RIGHT MAIN STEM BRONCHUS WITH REVERSED S SIGN OF GOLDEN
This combination of images shows the manifestations of a malignant mass in the hilum causing compression of the right mainstem bronchus. The PA CXR shows signs of volume loss (atelectasis characterized by elevation of the right hemidiaphragm (black arrowhead), rightward tracheal and mediastinal shift (white arrowheads) and elevation of the minor fissure contributing to the reverse S sign of Golden. There is a vague infiltrate in the right upper lobe correlating with an anterior pie shaped density of the lateral (blue arrowheads), consistent with collapse of the anterior segment of the RUL

OCCLUDED RIGHT MAIN STEM BRONCHUS WITH REVERSED S SIGN OF GOLDEN
This combination of images shows the manifestations of a malignant mass in the hilum causing compression of the right mainstem bronchus. There is elevation of the right hilum on the CXR, associated with collapse of the anterior segment of the RUL seen as a vague density in the P-A . The tomogram (3a) shows an abrupt cut off of the right mainstem bronchus while the overlay in 3b shows the occlusion of the right mainstem bronchus, the implied tumor overlaid in green. Images 4a and 4b are the correlative gross pathology images showing the tumor in green pushing  and occluding the right mainstem

Golden S sign

 

Golden S sign. Patient with right upper lobe collapse. Frontal chest radiograph (A) shows an abnormal convexity in the right perihilar region creating a rounded inferior border with the displaced minor fissure and the “reverse S” of right upper lobe collapse. The CT correlates to this finding (B) with retraction of the minor fissure superiorly and collapse of the involved segment medially against the mediastinum due to an adenocarcinoma occluding the right upper lobe bronchus.

Occluded Main Stem Bronchus, Atelectasis of the Right Lung, and Pleural Effusion
59F shows total white out caused by collapse of right lung with an
occluded right main step bronchus associated with a large right sided effusion. The occlusion is likely due to proximal cancer. A pigtail drain has been placed to drain the effusion
