HORSE SHOE LUNG

Horseshoe Lung – Overview

Horseshoe lung is a rare congenital lung anomaly where the lungs are fused across the midline behind the heart, typically associated with Scimitar Syndrome (a form of partial anomalous pulmonary venous return).

Key Features:

• Lung Fusion: The lower lobes of both lungs are connected by lung tissue crossing the midline.
• Scimitar Syndrome Association: Often coexists with right lung hypoplasia and anomalous pulmonary venous drainage.
• Airway and Vascular Anomalies: Can include tracheal stenosis, abnormal bronchial branching, or pulmonary artery anomalies.
• Symptoms: Respiratory distress, recurrent pneumonia, or may be asymptomatic and found incidentally.
• Diagnosis:
  • Chest X-ray & CT scan: Show fused lung tissue.
  • MRI or Angiography: Helps assess vascular anomalies.
