Radiologic Findings

Brief Review

Mucoid impaction of segmental and subsegmental bronchi is well-known to occur as a manifestation of a hypersensitivity state, usually in patients with asthma and in association with hypersensitivity bronchopulmonary aspergillosis. However, there are so many causes that can provoke the impaction of inspissated secretions within the bronchial tree. Those are obstructing endobronchial lesions at the segmental or subsegmental levels such as primary and metastatic carcinomas, carcinoid tumor, congenital bronchial atresia, and foreign body. In our country, Korea, endobronchial tuberculosis with bronchial stenosis can be an important cause. The affected bronchi are almost invariably dilated. The combination of the mucoid impaction and the well-functioning collateral air drift makes the mucoid impaction visible on chest radiograph. The radiological findings are an opacity with linear or branched- V or Y configuration, a zone of radiolucency caused by air-trapping and resultant oligemia.
