Abstract

High-attenuation mucus plugging is a rare finding in both adults and children. When it occurs, the field of differential diagnoses is typically quite small and includes acute hemorrhage, aspiration of radiodense material, and allergic bronchopulmonary aspergillosis (ABPA). The last of these three diagnoses is the most difficult to make, although ABPA is more commonly seen in children with cystic fibrosis (CF) or asthma. ABPA is radiographically characterized by recurrent mucus plugging, atelectasis, and central bronchiectasis. Thus far, high-attenuation mucus plugs have only been reported in adults. We report a rare case of a child with CF who had high-attenuation mucus plugs and atelectasis that raised the possibility of ABPA. We discuss the differential diagnoses of this finding and the role of multidetector CT in these children.
