Pulmonary sequestration

Pulmonary sequestration is a uncommon congenital, meaning present from birth, condition where a portion of lung tissue develops without a normal connection to the airways or pulmonary blood supply. It often causes no symptoms and is found unexpectedly. An MRI may show an abnormal area of lung tissue with a separate blood supply consistent with sequestration. Finding pulmonary sequestration early may allow for surgical planning before it causes recurrent infections or complications. CT is generally preferred for detailed lung assessment, however MRI can characterise the vascular supply of a sequestration effectively.
