This is a radiograph demonstrates peribronchial cuffing, which is increased density around the bronchioles when viewed end-on. This may represent thickening of the wall itself or fluid around the wall due to lymphatic congestion. The finding is nonspecific and can be seen in pulmonary edema, infectious and inflammatory bronchiolitis, and reactive airway disease. This particular case was a toddler with a previous diagnosis of asthma who presented to the emergency department with an acute asthma exacerbation.
