Congenital Lung Malformations (CLM)

Structural Lung Abnormalities Present Since Birth

Congenital Lung Malformations are developmental abnormalities of the lungs that occur before birth. These may include abnormal lung tissue, cysts, or airway malformations, which can lead to breathing issues, recurrent infections, and long-term lung damage.

What are Congenital Lung Malformations?

These are structural abnormalities present at birth that affect normal lung development.

CPAM
Congenital Pulmonary Airway Malformation
Bronchopulmonary Sequestration
Abnormal lung tissue with separate blood supply
Congenital Lobar Emphysema
Overinflated lung lobe
Bronchogenic Cyst
Cystic mass in the chest
Compress normal lung tissue
Impair airflow
Increase infection risk
Symptoms from early life → Important diagnostic clue

Congenital lung malformations may remain undiagnosed until adulthood. Early evaluation is critical.

Understanding

What are Congenital Lung Malformations?

These are structural abnormalities present at birth that affect normal lung development.

Common types include:

  • Congenital Pulmonary Airway Malformation (CPAM)
  • Bronchopulmonary Sequestration
  • Congenital Lobar Emphysema
  • Bronchogenic cyst

These abnormalities may:

  • Compress normal lung tissue
  • Impair airflow
  • Increase infection risk
Types

Types of Congenital Lung Malformations

CPAM

Congenital Pulmonary Airway Malformation

Abnormal lung tissue with cysts

Bronchopulmonary Sequestration

Abnormal lung tissue with separate blood supply

Doesn't connect to airways

Congenital Lobar Emphysema

Overinflated lung lobe

Can compress other structures

Bronchogenic Cyst

Cystic mass in the chest

May become infected

Warning Signs

Early Signs & Symptoms

In Infants
Difficulty breathing
Tachypnea
Rapid breathing
Increased respiratory rate
Feeding difficulty
Poor weight gain
In Children
Recurrent chest infections
Pneumonia
Chronic cough
Persistent
Wheezing
Airway obstruction
In Adolescents/Adults
Persistent respiratory symptoms
Long-standing
Breathlessness
On exertion
Reduced lung function
Detected on PFT
Risk Factors

Causes & Risk Factors

Cause

Abnormal lung development during pregnancy

Risk Factors
  • Usually sporadic (no clear cause)
  • Rare genetic associations
Progression

Disease Progression

Mild Cases Asymptomatic
Moderate Cases Recurrent infections
Severe Cases Significant lung damage
End Stage Respiratory failure

Mild Cases

Asymptomatic or minimal symptoms

May be discovered incidentally

Observation

Moderate Cases

Recurrent infections

Functional impairment

Surgical Treatment

Severe Cases

Significant lung damage

Reduced oxygen levels

Oxygen Therapy

End Stage Lung Disease

Respiratory failure

Lung transplant required

Lung Transplant

Assess long-standing lung symptoms early

Testing

Diagnosis & Tests

Prenatal ultrasound
Detects in some cases
Chest X-ray
Initial screening
HRCT scan
Key diagnostic test
Pulmonary function tests
Assess functional impairment

Assess your congenital lung risk

Early diagnosis prevents complications

Management

Treatment Options (Before Transplant)

1. Observation
  • In mild, asymptomatic cases
  • Regular monitoring
2. Surgical Treatment
  • Removal of abnormal lung segment
3. Infection Management
  • Antibiotics
4. Pulmonary Rehabilitation
  • Breathing exercises

When is Lung Transplant Needed?

Extensive lung involvement

Severe functional impairment

Recurrent complications

Oxygen dependency

Early Intervention Improves Outcomes

Surgical correction in early stages can prevent complications

Important Consideration: Lifelong Impact

• Present from birth • May remain undiagnosed until adulthood • Early evaluation is critical

Medical/Surgical vs Transplant
Medical/Surgical

Stage: Early/Moderate • Goal: Correct abnormality • Outcome: Often effective

Lung Transplant

Stage: Advanced • Goal: Replace lungs • Outcome: Life-saving

Frequently Asked Questions

Some can be surgically corrected.

No, mild cases may only need monitoring.

Only in rare severe cases.

Congenital lung malformations vary widely in severity.
