These occur within the existing membrane or the visceral pleura of the lungs. Also presents in adults after the age of 20, most patients are asymptomatic and have these abnormalities for years and are only diagnosed during routine chest x-rays for unrelated issues.
2. Extralobar Sequestrations are less common approximately 15%-20%. These usually present in the neonate with respiratory distress, cyanosis and or infection. This type is completely enclosed in their own pleural sac. These are common in neonates and unborn babies that are likely to develop other malformations like heart defects and GI deformities.
