Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1] This causes the area around the bronchus to appear more prominent on an X-ray ...
For lung nodules, air bronchograms used to be associated with infectious causes of consolidation and, therefore to be benign. However, in the setting of a lung nodule, an air bronchogram is actually more frequent in malignant than in benign nodules. [1] [4] studied the tumour-bronchus relationship and described five types: [1]
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign.
The air bronchogram sign, where branching radiolucent columns of air corresponding to bronchi is seen, usually indicates air-space (alveolar) disease, as from blood, pus, mucus, cells, protein surrounding the air bronchograms. This is seen in Respiratory distress syndrome [9]

Small nodular opacities occur in up to 50% of patients and large nodules in 15%. On high resolution computed tomography, airspace consolidation with air bronchograms is present in more than 90% of patients, often with a lower zone predominance. A subpleural or peribronchiolar distribution is noted in up to 50% of patients.
Hints and the solution for today's Wordle on Wednesday, January 15.
Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange , most often leading to shortness of breath ( dyspnea ) which can progress to hypoxemia and respiratory failure .
