Summary
A rare case of intralobar pulmonary sequestration was diagnosed in an asymptomatic young woman. A large anomalous artery from the aorta supplied the affected lung lobe, causing a continuous murmur.
Area of Science:
- Cardiovascular Medicine
- Pulmonary Medicine
- Radiology
Background:
- Pulmonary sequestration is a rare congenital lung malformation.
- It can present with diverse clinical and radiological findings.
- Early diagnosis is crucial for appropriate management.
Observation:
- An 18-year-old asymptomatic female presented with a continuous murmur.
- Chest X-ray showed mild left lower lung haziness; echocardiogram was normal.
- A large anomalous systemic artery originated from the descending thoracic aorta.
Findings:
- The anomalous artery supplied the left lower lung lobe, consistent with intralobar pulmonary sequestration.
- Bronchoscopy revealed normal bronchial connections.
- Delayed dye clearance from bronchioles confirmed intralobar sequestration.
Implications:
- The continuous murmur was attributed to high flow in the anomalous artery.
- This case highlights the importance of considering vascular anomalies in congenital lung malformations.
- Accurate diagnosis requires a multidisciplinary approach involving imaging and bronchoscopy.
