The imaging spectrum of bronchopulmonary sequestration

Area of Science:

• Radiology
• Thoracic Imaging
• Pulmonology

Background:

• Bronchopulmonary sequestration (BPS) is a congenital lung malformation.
• It features abnormal lung tissue lacking normal bronchial connections.
• BPS receives blood supply from anomalous systemic arteries.

Purpose of the Study:

• To review the diverse imaging spectrum of BPS.
• To highlight important parenchymal mimics of BPS.
• To discuss conditions with similar anomalous systemic arterial supply to the lung.

Main Methods:

• Review of imaging findings in BPS.
• Comparison with differential diagnoses.
• Analysis of anatomical variations in systemic arterial supply to the lung.

Main Results:

• BPS presents with varied imaging appearances: consolidation, mass, or cystic lesions.
• Key parenchymal mimics include pneumonia, tumors, and congenital cysts.
• Conditions with anomalous systemic arterial supply share imaging overlap with BPS.

Conclusions:

• Understanding the imaging spectrum of BPS is crucial for accurate diagnosis.
• Differentiating BPS from its mimics requires careful evaluation of imaging features.
• Awareness of conditions with anomalous systemic arterial supply aids in differential diagnosis.
