“…The predilection for this age group is hypothesized to be due to their underlying anatomy: increased chest wall elasticity and pliability facilitates enhanced transfer of the traumatic impact into lung parenchyma. This increased elasticity and recoil result in larger changes in intrathoracic pressure, leading to parenchymal injury and disruption, and subsequent development of air-filled cavitations and pneumatoceles [1, 7]. The adult chest wall becomes increasingly stiff and less compliant as developmental changes ensue [8].…”

Pulmonary pneumatocele is a cystic, air-filled lesion in the lung parenchyma. It results from underlying inflammation or bronchial injury. It is seen in several lung pathologies including bacterial pneumonia, positive-pressure ventilation, chest trauma, chemical pneumonitis, and is most often seen in infants and children. On imaging, pneumatoceles appear as rounded, thin-walled, air-filled spaces in the lung parenchyma. The exact mechanism for forming pneumatoceles is not fully understood but thought to be due to a check-valve mechanism due to obstruction by inflammation causing air trapping in the damaged lung. These lesions are asymptomatic and transient in most patients and disappear by about 6 weeks. They usually do not require any specific treatment or intervention. Surgical intervention is only necessary when pneumatoceles cause cardiopulmonary compromise or rupture into the pleural space. We describe a case of a young adult who developed a pneumatocele after developing acute respiratory distress syndrome from community-acquired pneumonia treated with positive-pressure ventilation. He was managed conservatively with complete resolution of symptoms.
