Overview

Overview

A pneumatocele, or pneumatocyst is a cavity in the lungs filled with air that may result from pulmonary trauma.[1] A pneumatocele results when a lung laceration, a cut or tear in the lung tissue, fills with air.[2] A rupture of a small airway creates the air-filled cavity.[1] Pulmonary lacerations that fill with blood are called pulmonary hematomas.[2] In some cases, both pneumatoceles and hematomas exist in the same injured lung.[3] A pneumatocele can become enlarged, for example when the patient is mechanically ventilated or has acute respiratory distress syndrome, in which case it may not go away for months.[3] Diagnosis can be made using chest X-ray; the lesion shows up as a small, round area filled with air.[1] Computed tomography can give a more detailed understanding of the lesion.[1] Differential diagnoses, other conditions that could cause similar symptoms as pneumatocele, include lung cancer, tuburculosis, and a lung abscess.[1] Treatment includes monitoring and pulmonary toilet (the use of methods such as positioning and suction to keep the airways clear of secretions).[1]
