Abstract:
Pseudomembranous aspergillus bronchitis is considered as an early form of invasive pulmonary aspergillosis, a well-known airway infection in immunocompromised patients. Radiologic features concerning invasive aspergillosis of the airways have been reported. However, we describe here an unusual feature of invasive aspergillus bronchitis, never reported to date, observed in a double-lung transplanted patient. Chest radiograph and CT revealed significant peribronchial thickening without any parenchymal involvement.
Insights
Pseudomembranous aspergillus bronchitis, an early invasive pulmonary aspergillosis form, typically affects immunocompromised patients. This study highlights an unusual radiologic finding of peribronchial thickening without parenchymal involvement in a double-lung transplant recipient.
Area of Science:
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- Pseudomembranous aspergillus bronchitis is an early manifestation of invasive pulmonary aspergillosis.
- It primarily affects immunocompromised individuals, particularly those with airway infections.
- Radiologic findings of invasive aspergillosis in airways are documented.
Observation:
- This report details an unprecedented radiologic feature of invasive aspergillus bronchitis.
- The observation was made in a patient who had undergone a double-lung transplantation.
- The patient presented with significant peribronchial thickening.
Findings:
- Chest radiography and computed tomography (CT) revealed distinct peribronchial thickening.
- Crucially, there was a complete absence of parenchymal involvement.
- This presentation is atypical for previously reported cases.
Implications:
- This finding expands the spectrum of radiologic manifestations for invasive aspergillus bronchitis.
- It underscores the importance of considering unusual presentations in transplant recipients.
- Further research may be needed to understand this specific radiologic pattern.
