Failure to have a pulmonary sequestration removed can leads to a number of complications.

CT scans have 90% accuracy in the diagnosis of pulmonary sequestration.

Pulmonary sequestrations usually get their blood supply from the thoracic aorta.

The blood supply of 75% of pulmonary sequestrations is derived from the thoracic or abdominal aorta.

In children, recurrent episodes of CAP may be the first clue to diseases such as cystic fibrosis or pulmonary sequestration.

Congenital malformations such as pulmonary sequestration and congenital cystic adenomatoid malformation (CCAM).

Associated abnormalities include right lung hypoplasia with associated dextroposition of the heart, pulmonary artery hypoplasia and pulmonary sequestration.

(intrapulmonary sequestration drains via pulmonary veins, extra pulmonary sequestration drains to the IVC)

Less common causes of a solitary pulmonary nodule include hamartomas, bronchogenic cysts, adenomas, arteriovenous malformation, pulmonary sequestration, rheumatoid nodules, Wegener's granulomatosis, or lymphoma.

Contrast-enhanced MRA or even conventional T1-weighted spin-echo (SE) images may help in the diagnosis of pulmonary sequestration by demonstrating a systemic blood supply, particularly from the aorta, to a basal lung mass.

A pulmonary sequestration (also known as a bronchopulmonary sequestration or cystic lung lesion), is a medical condition wherein a piece of tissue that ultimately develops into lung tissue is not attached to the pulmonary arterial blood supply, as is the case in normally developing lung.
