Peribronchial cuffing
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. It has also been described as donut sign, considering the edge is thicker, and the center contains air.
Peribronchial cuffing is seen in a number of conditions including:
- Acute bronchitis
- Asthma following exercise or during an acute episode
- Bronchiolitis
- Bronchopulmonary dysplasia
- Congestive heart failure
- Cystic fibrosis
- Diffuse parenchymal lung disease
- Extreme exertion through physical exercise
- Hantavirus pulmonary syndrome
- Human metapneumovirus
- Kawasaki disease
- Lung cancer
- Pneumonia
- Pulmonary edema
- Smoke inhalation
Treatment
As peribronchial cuffing is a sign rather than a symptom or condition, there is no specific treatment except to treat the underlying cause.
