Abstract

Background: Pulmonary sequestration may be intralobar or extralobar. Intralobar pulmonary sequestration occurs most often in the left lower lobe, and symptoms first occur around the age of 20. By contrast, extralobar pulmonary sequestration is restricted to the lower lobes and presents from the neonatal period. Diagnosis is suggested by chest X-ray and confirmed by computed tomography angiography. Treatment comprises vessel ligation and resection to prevent repeated chest infections and complications. 
Case Presentation: We describe an 18-year-old woman who was admitted to our hospital with a history of repeated chest infection in the left lower lobe over the last two years. She was found to have intralobar pulmonary sequestration, which was managed by left lower lobectomy.
Conclusion: Pulmonary sequestration is a rare condition but should be suspected in patients with repeated pneumonia in the same lung in early adulthood.

Key words: Pulmonary sequestration, Intralobar sequestration, Recurrent pneumonia, Same side chest infection, Extralobar pneumonia, Complications of pulmonary sequestration.
