Summary
This study presents three adult intrapulmonary sequestration cases in women, diagnosed via imaging and treated with lobectomy due to recurrent infections. The findings suggest an acquired origin, as infantile infections were absent and Pryce
Area of Science:
- Pulmonology
- Thoracic Surgery
- Radiology
Background:
- Intrapulmonary sequestration is a rare congenital lung malformation.
- Adult-onset presentations are less common and often misdiagnosed.
- Recurrent bronchopulmonary infections are a frequent complication.
Observation:
- Three adult female patients (ages 22-49) presented with intrapulmonary sequestration.
- Radiological findings included abnormal lower lobe shadows on chest X-rays.
- Aortography revealed aberrant arteries, confirming intrapulmonary sequestration preoperatively.
Findings:
- All cases underwent lobectomy due to recurrent infections.
- Pryce's classification was challenging due to unclear margins between sequestrated and normal lung tissue.
- Absence of infantile infection history supports an acquired origin theory for these cases.
Implications:
- Highlights the importance of considering intrapulmonary sequestration in adults with recurrent lower respiratory tract infections.
- Suggests that acquired factors may play a significant role in the pathogenesis of some intrapulmonary sequestration cases.
- Underscores the limitations of current classification systems for complex or atypical presentations.
