Pneumatocele
From Wikipedia, the free encyclopedia
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]
