55-year-old male presenting with dyspnea
Frontal CXR shows right upper lobe (RUL) atelectasis characterized by rightward deviation of the trachea elevation of the right hemidiaphragm and opacification of the right upper lobe. Final diagnosis was a central RUL proximal squamous cell carcinoma with extensive filling of the distal bronchi-ectatic segmental and subsegmental airways

Lateral CXR confirms atelectasis of the RUL characterized by pie shaped consolidation of the anteriorly position right upper lobe, hyperinflation of the right lower lobe mild elevation of the right hemidiaphragm. Final diagnosis was a central RUL proximal squamous cell carcinoma with extensive filling of the distal bronchi-ectatic segmental and subsegmental airways

55-year-old male presenting with dyspnea
Axial CT at the level of the carina shows atelectasis of the RUL caused by a central obstructing lesion in the right upper lobe bronchus (b, white arrowhead) resulting in atelectasis of the RUL characterized by a wedge-shaped consolidation of the anteriorly positioned right upper lobe. The major fissure is displaced anteriorly (a, pink arrowhead). There is extensive filling of the distal bronchiectatic segmental and subsegmental airways of the RUL (b, yellow arrowheads). Final diagnosis was a central RUL proximal squamous cell carcinoma.

55-year-old male presenting with dyspnea
Coronal CT at the level of the trachea and mainstem bronchi, shows atelectasis of the RUL caused by a central obstructing lesion in the right upper lobe bronchus (b, white arrowhead) resulting in atelectasis of the RUL characterized by a wedge-shaped consolidation of the right upper lobe with superiorly displaced major fissure (a, pink arrowhead). There is extensive filling of the distal bronchiectatic segmental and subsegmental airways of the RUL (b, yellow arrowheads). Final diagnosis was a central RUL proximal squamous cell carcinoma.

Reversed S sign of Golden
The scout film performed prior to a CT scan from a 76-year-old man with chest pain and shortness of breath. The appearance suggests atelectasis of the right upper lobe with the normal position of the minor fissure (yellow) altered so that the upper portion (light green above the yellow line) is shifted upward caused by volume loss of an atelectatic right upper lobe (pink). The lower portion of the fissure (light green below the yellow line) is bulging rightward and outward caused by an implied mass (dark green). The “reversed S sign of Golden” is demonstrated in this case and infers a central mass causing obstruction and resulting in the shape described by the light green line of the minor fissure.

Aspiration
Aspiration of Solid Food Right and Left lower Lobe Bronchi
71-year-old male presents with acute respiratory difficulty. CT in the coronal plain shows solid food particles in right mainstem bronchus (yellow arrowhead), extending into the right lower lobe bronchus, as well as segmental airways to the left lower lobe (orange arrowheads). The right hemidiaphragm is elevated secondary to the atelectasis

71-year-old male presents with acute respiratory difficulty. CT in the axial plain shows solid food particles in the apical segment of the right lower lobe of the lung (b, yellow arrowheads) and in the left lower lobe (b, orange arrowheads) associated with bilateral basilar subsegmental atelectasis right greater than left (b, teal arrowheads).

Occlusion of the Right Main Stem Bronchus
74 year old male alcoholic with bilateral basilar lobar atelectasis caused by bilateral aspiration
