Presentation
Cough and shortness of breath in a known case of asthma.
Patient Data
There are mixed saccular, cystic and cylindrical bronchiectasis changes in the left upper lobe including the lingular lobe.
Multiple patchy areas of centrilobular nodules are scattered in the left lower lobe and right upper lobe.
A few high attenuation mucous (HAM) plugs are scattered in the left lower lobe.
Case Discussion
The HRCT thorax findings are suggestive of allergic bronchopulmonary aspergillosis (ABPA). It is the mild form of the spectrum of disease caused by pulmonary aspergillosis and is commonly seen in asthmatic patients.
High-attenuation mucus (HAM) is often considered a characteristic and an "almost pathognomonic" feature of allergic bronchopulmonary aspergillosis (ABPA).
