To describe the clinical, radiographic, and pathologic characteristics of ventilator-induced subpleural air cysts in patients receiving mechanical ventilation for adult respiratory distress syndrome.
Reviewed clinical courses, radiographic findings, and pathologic features in a case series of adult patients (N=5) undergoing treatment for adult respiratory distress syndrome.
Evaluated the impact of elevated ventilator airway pressures, pressure reduction strategies, and chest tube interventions on patient outcomes.
Subpleural air cysts presented as thin-walled, rounded gas collections resulting from high airway pressures, alveolar rupture, and peripheral gas dissection, serving as an identifiable early marker of barotrauma.
Tension pneumothorax developed rapidly following cyst formation when airway pressures were not decreased or chest tubes were not pre-emptively inserted.
Secondary bacterial infection of the cysts occurred frequently, contributing substantial additional morbidity to the clinical course.

Implication

Case series reveals subpleural air cysts precede tension pneumothorax in adults with respiratory distress syndrome, indicating an early radiographic warning sign of pulmonary barotrauma.
