[A case of systemic arterialization of lung without sequestration]

Area of Science:

• Cardiovascular Medicine
• Pulmonary Medicine
• Congenital Diseases

Background:

• Intralobar pulmonary sequestration is a congenital lung anomaly involving nonfunctioning tissue and systemic arterial supply.
• Understanding the spectrum of sequestration complex is crucial for accurate diagnosis and management.

Observation:

• A rare case of anomalous systemic arterial supply to the lung, without associated pulmonary sequestration, was identified.
• This case presented without any demonstrable pulmonary changes, challenging typical sequestration definitions.

Findings:

• The case highlights the existence of systemic arterialization of the lung as a distinct entity.
• It raises questions about its classification as a subtype of pulmonary sequestration.

Implications:

• This finding expands the understanding of congenital pulmonary vascular anomalies.
• Further research is needed to clarify the classification and clinical significance of systemic arterialization without sequestration.
