Pulmonary alveolar derecruitment is a process of alveolar collapse that occurs in critically ill patients. While the entity and its physiological manifestations are described in the anesthesiology and critical care literature, the radiographic manifestations of alveolar derecruitment have not yet been thoroughly described. This phenomenon can have a similar appearance to pulmonary edema; however, patients often have severe intravascular volume depletion. As the treatment for these 2 entities is essentially contradictory, it is important to be familiar with alveolar derecruitment and consider it as a differential diagnosis when clinically appropriate.
