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.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
