Pneumatocele

Large, right lower lobe pneumatocele is shown, compromising ventilation in a premature infant with RDS and superimposed RSV pneumonitis.

A pneumatocele is a cavity in the lung parenchyma filled with air that may result from pulmonary trauma during mechanical ventilation.[1]

Gas-filled, or air-filled lesions in bone are known as pneumocysts.[2] When a pneumocyst is found in a bone it is called an intraosseous pneumocyst, or a vertebral pneumocyst when found in a vertebra.[3]
