Objective:
Pulmonary sequestration (PS) is an uncommon congenital disease. Symptoms when present are usually secondary to pyogenic infection. Our objective was to draw attention on superimposed fungal infection.
Methods:
During the last 20 years, we operated upon 19 intralobar PS. Four of six patients operated during the last decade proved to have intralobar PS containing Aspergillus.
Results:
In one patient aspergillosis presented as an aspergilloma and communications between the sequestration and small bronchi were present. In another patient diagnosis was made before operation because of positive precipitins test. In two patients aspegillosis was discovered by the pathologist.
Conclusions:
Review of literature demonstrates PS fungal colonization to be a rare but recently reported entity (14 cases reported). The observation of four consecutive patients leads us to suggest that PS aspergillosis must be considered in order to evaluate its incidence.
Insights
Pulmonary sequestration (PS) can develop superimposed fungal infections, particularly Aspergillus. This study highlights the need to consider fungal colonization in PS patients to determine its true incidence.
Area of Science:
- Medicine
- Pulmonology
- Infectious Diseases
Background:
- Pulmonary sequestration (PS) is a rare congenital lung malformation.
- Symptoms of PS are typically linked to secondary bacterial infections.
Observation:
- This study reviewed 19 cases of intralobar PS operated on over 20 years.
- A significant proportion (4 out of 6) of patients operated on in the last decade had intralobar PS with Aspergillus.
Findings:
- Aspergillosis in PS manifested as aspergilloma with bronchial communication in one case.
- Preoperative diagnosis of aspergillosis was possible in one patient via a positive precipitins test.
- Pathological examination confirmed aspergillosis in two additional patients.
Implications:
- Fungal colonization, specifically aspergillosis, is an under-recognized complication of pulmonary sequestration.
- Increased awareness and diagnostic consideration are necessary to accurately assess the incidence of PS aspergillosis.
- Further research is warranted to understand the pathogenesis and optimal management of this rare entity.
