Pulmonary Sequestration ; Differences between Intralobar and Extralobar Lung sequestration

Pulmonary sequestration is a congenital malformation where a portion of lung tissue is not connected to the bronchial tree and receives its blood supply from an abnormal artery. There are two types of pulmonary sequestration: intralobar and extralobar. Here are the key differences between them: Intralobar Pulmonary Sequestration (ILS) Location: Located within a normal lobe of the lung. Pleura: Does not have its own visceral pleura. Presentation: Typically presents later in childhood or adolescence with recurrent pulmonary infections. Venous Drainage: Usually drains into the pulmonary veins, but can also drain into the systemic veins. Common Symptoms: Recurrent pneumonia, cough, chest pain, and hemoptysis (coughing up blood). Extralobar Pulmonary Sequestration (ELS) Location: Located outside the normal lung and has its own visceral pleura. Pleura: Has its own separate pleura. Presentation: Typically presents in the neonatal period with respiratory distress, cyanosis, or infection. Venous Drainage: Usually drains into the systemic veins, often the right atrium. Common Symptoms: Respiratory distress, cyanosis, and recurrent infections in newborns. Both types of pulmonary sequestration are supplied by an aberrant artery, usually from the aorta. Surgical removal is often the treatment of choice to prevent recurrent infections and other complications. #PulmonarySequestration
