Summary

Pulmonary sequestrations often present as atypical or complex anomalies, not just classic isolated lesions. Understanding this spectrum is crucial for accurate diagnosis and appropriate surgical management.

Area of Science:

Pediatric Surgery
Thoracic Surgery
Congenital Anomalies

Background:

Pulmonary sequestration (PS) is a rare congenital lung malformation.
This study aimed to characterize atypical PS and associated anomalies.

Observation:

Only 56% of reviewed cases had classic isolated PS; the rest had associated anomalies.
Prenatally diagnosed PS were often asymptomatic at birth, while postnatal diagnoses were symptomatic.
Preoperative diagnosis accuracy was 59%, with most patients undergoing resection.

Findings:

PS represent a spectrum of anomalies overlapping with other lung lesions.
Atypical PS or those with associated anomalies are common, occurring in approximately 50% of cases.
Associated anomalies include congenital cystic adenomatoid malformations, bronchopulmonary foregut malformations, bronchogenic cysts, and scimitar syndrome.

Implications:

A comprehensive descriptive approach is needed for PS management, considering various anatomical and pathological features.
Surgeons must consider the high prevalence of atypical PS when deciding between resection and conservative management.
Accurate preoperative diagnosis and understanding of associated anomalies are vital for optimal patient outcomes.
