Summary
Allergic bronchopulmonary aspergillosis (ABPA) diagnosis can be challenging, even with extensive prior investigations. This case highlights the importance of considering ABPA in chronic cough, with central bronchiectasis being a key diagnostic indicator.
Area of Science:
- Pulmonology
- Allergy and Immunology
- Medical Mycology
Background:
- Allergic bronchopulmonary aspergillosis (ABPA) is an immunologic lung disease caused by Aspergillus species colonization.
- ABPA is characterized by bronchial asthma, pulmonary infiltrates, eosinophilia, and bronchiectasis.
- The condition is uncommon in Taiwan, complicating diagnosis.
Observation:
- A patient presented with a 5-year history of chronic asthmatic-like cough, with prior extensive but inconclusive investigations.
- Sputum eosinophilia prompted consideration of eosinophilic lung diseases.
- A bronchogram revealed central bronchiectasis, a crucial finding for diagnosis.
Findings:
- The diagnosis of allergic bronchopulmonary aspergillosis was established.
- Diagnosis was made despite negative sputum cultures for Aspergillus fumigatus and absent serum precipitins.
- Central bronchiectasis was the key diagnostic feature in this challenging case.
Implications:
- This case underscores the importance of recognizing ABPA in patients with chronic cough and asthma-like symptoms.
- Diagnostic challenges highlight the need for comprehensive evaluation, including bronchography.
- Early and accurate diagnosis of ABPA is crucial for appropriate management and preventing further lung damage.
