Lungs
2. Findings and Diagnosis
lungs-0030-low-res.jpg : The Acinus The acinus is defined as a unit of lung consisting of a single first order respiratory bronchiole that subtending a cluster of alveoli reminiscent of a bunch of grapes or berries (acinus in Latin means berry) . The lobular bronchiole (lb) branches into the terminal bronchiole (tb), which then branches into the first order respiratory bronchiole (rb). Subsequent branching after the respiratory bronchiole, includes in order, the alveolar duct (ad), alveolar sac (as), and then finally the berry like alveoli.

CXR Right Upper Lobe Collapse Squamous Cell Carcinoma
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

| CXR Finding | Description |
|---|---|
| Shift of the mediastinum | The mediastinum may shift towards the side of the collapse due to volume loss in the right upper lobe. |
| Elevation of the right hemidiaphragm | The right diaphragm may appear elevated as a result of the collapse in the right upper lobe. |
| Displacement of the right hilum | The hilum may appear displaced upward or inward due to volume loss in the affected lung. |
| Air bronchogram | In some cases, an air bronchogram (visible air-filled bronchi surrounded by opaque lung tissue) may be seen if there is consolidation or atelectasis present. |
| Opacity in the right upper zone | A dense opacity may be visible in the right upper lobe due to consolidation or atelectasis. |
| Loss of right upper lobe outline | The normal clear demarcation of the right upper lobe may be absent or indistinct due to the collapse. |
| Hyperinflation of the left lung | The left lung may appear hyperinflated due to compensatory expansion from the collapse of the right upper lobe. |
| Flattening of the right costophrenic angle | This may occur due to the altered lung volume and diaphragm position resulting from the collapse. |
| Reversed Sign of Golden | The “Golden Sign” refers to the upward displacement of the minor fissure seen in right upper lobe collapse, but in this case, the minor fissure may be displaced downward, creating a “reversed” sign. |
The Reversed Sign of Golden occurs due to the altered position of the right upper lobe fissures in the setting of a collapse, where the minor fissure may be displaced downward instead of upwards as seen in typical consolidation or collapse patterns.
