Pulmonary Sequestration: Causes, Signs, and Treatment
Pulmonary sequestration is a rare condition where abnormal lung tissue develops separately from the normal lung. This extra lung tissue doesn't function like a regular lung and doesn't participate in breathing. It can impact a person's health by potentially causing respiratory issues or complications due to the abnormal structure within the chest cavity. Identifying and managing pulmonary sequestration is essential to prevent any potential health risks associated with this condition.
Symptoms of Pulmonary Sequestration
Individuals with Pulmonary Sequestration may experience respiratory-related symptoms that can vary in severity.
- Chest pain
- Coughing up blood
- Shortness of breath
- Recurrent respiratory infections
- Wheezing or noisy breathing
- Difficulty breathing
- Chest tightness
- Fatigue

Get Second OpinionCauses of Pulmonary Sequestration
Pulmonary sequestration is typically caused by an abnormal development of lung tissue during fetal growth.
Causes of Pulmonary Sequestration:
- Congenital anomaly
- Developmental abnormality
- Unknown factors
Types of Pulmonary Sequestration
Pulmonary sequestration can present in different forms, each with distinct characteristics and implications for diagnosis and treatment.
- Intralobar Sequestration: A type of pulmonary sequestration where the abnormal lung tissue is within the normal lung's lobe.
- Extralobar Sequestration: In this type, the sequestered lung tissue is separate from the normal lung and has its own pleural covering.
- Mixed Sequestration: A combination of intralobar and extralobar sequestration, involving both types of lung tissue abnormalities.
- Cystic Sequestration: Characterized by the presence of cysts within the sequestered lung tissue.
- Solid Sequestration: Refers to sequestered lung tissue that lacks cysts and is predominantly solid in nature.
Risk Factors
Pulmonary sequestration, a rare congenital lung malformation, occurs due to abnormal lung tissue development during fetal growth.
- Congenital abnormality
- Smoking during pregnancy
- Family history of lung disorders

Diagnosis of Pulmonary Sequestration
Pulmonary sequestration is typically diagnosed through a combination of imaging tests and clinical evaluations by healthcare providers.
- Imaging tests, such as CT scan and MRI
- Angiography
- Bronchoscopy
Treatment for Pulmonary Sequestration
Pulmonary sequestration is typically managed through medical interventions to alleviate symptoms and prevent complications.
Surgical Resection:
- The main treatment for pulmonary sequestration involves surgical removal of the abnormal lung tissue to prevent complications and improve symptoms.
Embolization:
- Embolization is a minimally invasive procedure where tiny particles are injected into the blood vessels feeding the sequestrated lung tissue to block blood flow and shrink the abnormal tissue.
Observation:
- In cases where the pulmonary sequestration is small and asymptomatic, doctors may choose to monitor the condition over time with regular checkups instead of immediate intervention.
Antibiotics:
- Antibiotics may be prescribed if there is an infection present in the sequestered lung tissue to help clear the infection and prevent further complications.
Symptom Management:
- Symptoms such as cough, chest pain, or recurrent infections associated with pulmonary sequestration can be managed with medications to improve quality of life while monitoring the condition.

What is pulmonary sequestration?
Pulmonary sequestration is a rare congenital condition where a mass of lung tissue does not function as part of the normal lung and receives its blood supply from an abnormal source.
What are the symptoms of pulmonary sequestration?
Symptoms may include recurrent respiratory infections, chest pain, coughing up blood, and difficulty breathing. Some patients may be asymptomatic.
How is pulmonary sequestration diagnosed?
Diagnosis typically involves imaging studies such as CT scans or MRI, as well as angiography to identify the abnormal blood supply to the sequestered lung tissue.
What treatment options are available for pulmonary sequestration?
Treatment options may include observation, surgical resection of the affected lung tissue, or embolization of the abnormal blood vessels feeding the sequestered lung.
What is the prognosis for individuals with pulmonary sequestration?
With appropriate treatment, the prognosis for individuals with pulmonary sequestration is generally good. However, outcomes can vary depending on factors such as the size and location of the sequestered lung tissue.
