Summary

Pulmonary sequestration, a lung malformation, typically affects children. This case highlights an unusual adult presentation of extralobar sequestration as a retroperitoneal mass.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Pediatric Surgery

Background:

  • Pulmonary sequestration is a congenital lung malformation characterized by non-functional lung tissue lacking normal bronchial connections and receiving anomalous systemic arterial supply.
  • It is categorized into intralobar and extralobar types, differing in location and venous drainage patterns.
  • Extralobar sequestration, less common, often presents in childhood and typically involves systemic venous drainage into the azygos system.

Observation:

  • This report details an atypical case of extralobar sequestration.
  • The malformation manifested as a retroperitoneal mass.
  • The patient was an asymptomatic adult, deviating from the typical pediatric diagnosis.

Findings:

  • The case demonstrates extralobar sequestration presenting outside the thoracic cavity.

  • The retroperitoneal location is an unusual manifestation for this condition.
  • Diagnosis in adulthood without typical respiratory symptoms is noteworthy.

    • Implications:

    • This case expands the known clinical spectrum of pulmonary sequestration.
    • It underscores the importance of considering rare diagnoses in adults presenting with unusual masses.
    • Awareness of extralobar sequestration's varied presentations is crucial for accurate diagnosis and management.
