Abstract:
Allergic bronchopulmonary aspergillosis (ABPA) develops as the result of a hypersensitivity reaction to fungi of the genus Aspergillus. Clinical and radiological presentation can be atypical, requiring a high degree of suspicion on the part of the physician who treats such patients. We report the cases of two patients with APBA in whom the form of presentation--with few asthma symptoms, images showing lobar atelectasia and hilar adenopathy--led to an initial suspicion of lung cancer.
Insights
Allergic bronchopulmonary aspergillosis (ABPA) can present atypically, mimicking lung cancer. Early suspicion is crucial for timely diagnosis and treatment of this fungal hypersensitivity reaction.
Area of Science:
- Pulmonology
- Allergy and Immunology
- Mycology
Background:
- Allergic bronchopulmonary aspergillosis (ABPA) is an immune response to Aspergillus fungi.
- Diagnosis can be challenging due to atypical presentations.
Observation:
- Two cases of ABPA are presented.
- Patients exhibited minimal asthma symptoms, lobar atelectasis, and hilar adenopathy on imaging.
Findings:
- The clinical and radiological findings initially suggested lung cancer.
- ABPA diagnosis requires a high index of clinical suspicion.
Implications:
- This case series highlights the importance of considering ABPA in differential diagnoses.
- Physicians should be aware of unusual presentations to avoid misdiagnosis.
