Case ReportsPersistent pneumatoceles associated with systemic leukocyte abnormalities.
Three patients with leucocyte related immune deficiency developed pneumatoceles during acute bacterial pneumonia. A fourth patient with chronic granulomatous disease of childhood developed persistent lung cysts following pulmonary abscesses. ⋯ In 25 immunologically normal patients, pneumatoceles that were associated with acute bacterial pneumonia resolved in 3 weeks to 11 months. Perhaps alterations in leukocytic function and in local inflammatory response result in fibrotic cellular reaction and sequestration of parenchymal air collections, precluding their resorption.
