For example, thick white discharge could signify a yeast infection. If the discharge is a different color, it may be a sign of an infection. Normal vaginal discharge, also known as leukorrhea, is clear or white and is usually odorless or may have a mild smell.

Prolonged mucus plugging can lead to bronchial dilatation and bronchiectasis. congenital bronchial atresia, foreign body aspiration) Several key additional features can also occur:ĭistal lung collapse: from collateral air drift this has not yet developed in infants and young children, which is why the distal lung is rather hyperlucent in this population (e.g. The classic feature seen when plugged mucus extends along large branching airways is the finger-in-glove sign. Mucus plugs appear as fluid density material often located dependently within the bronchus, sometimes with internal gas. The appearance on CT can be variable, depending on where the mucus plugging occurs (i.e. This classic feature is the finger-in-glove sign and is also seen on CT. It can sometimes prove difficult to diagnose on plain radiography. Mucoid impaction may appear as a branching tubular opacity that is distinct from the normal vascular shadows. Non-obstructive causes are infectious or inflammatory in nature:Ĭystic fibrosis: due to impaired ciliary movement and thick secretionsĪsthma: due to increased mucus productionĪllergic bronchopulmonary aspergillosis (ABPA) - can sometimes have high attenuation mucoid impactionĬongenital bronchial atresia: most commonly affects the apicoposterior segment of the left upper lobe The presence of mucus plugging should be recognized as a treatable trait for patients with severe asthma in terms of targeting therapy with biologics. Mucoid impaction may result from either obstructive or non-obstructive causes, although the latter does eventually obstruct the bronchi as well: Non-obstructive
