Most lung hernias occur in which location?

• A. Thoracic
• B. Cervical
• C. Abdominal
• D. Diaphragmatic

Answer: (A)

Cervical (neck) is the most common location for lung hernias. This occurs because the lung apex and pleura extend into the neck through the thoracic inlet, where the suprapleural membrane (Sibson’s fascia) provides a potential weak spot. If this support is diminished—whether from congenital factors, trauma, or repeated increases in intrathoracic pressure—the apical lung tissue can protrude into the lower neck, producing a cervical hernia. Traumatic or high-pressure events (like coughing fits, heavy lifting, or blunt trauma) can push the lung tissue through this point, whereas hernias through the chest wall intercostally, the diaphragm, or the abdominal cavity are less common. While thoracic wall hernias do occur, they are comparatively rarer than the cervical variety.
