Middle lobe syndrome (MLS), a rare condition often diagnosed late, can cause recurrent pneumonia. Surgical resection (lobectomy) offers a cure for persistent atelectasis in children.

Area of Science:

  • Pulmonology
  • Pediatric Medicine
  • Thoracic Surgery

Background:

  • Middle lobe syndrome (MLS), also known as atelectasis syndrome, primarily affects the right middle lobe.
  • It is uncommon in children, accounting for only 15% of reported cases.

Purpose of the Study:

  • To present two pediatric cases of middle lobe syndrome.
  • To highlight diagnostic challenges and treatment outcomes for MLS in children.

Main Methods:

  • Chest radiography
  • Computed tomography (CT) scanning
  • Ventilation-perfusion scintigraphy
  • Flexible bronchoscopy
  • Lobectomy

Main Results:

  • Two boys, aged 4 and 12, presented with recurrent right middle lobe pneumonia.
  • Diagnostic workup revealed persistent atelectasis with reduced perfusion, leading to lobectomy.
  • Histology showed bronchial obstruction in the younger patient and chronic inflammation in both.

    • Conclusions:

    • Late diagnosis of MLS is common.
    • Persistent atelectasis unresponsive to medical therapy warrants consideration for lobectomy.
    • Surgical resection resulted in a cure for both pediatric patients.
