pneumatocele

 [noo-mat´o-sēl]
1. a tumor or cyst formed by air or other gas filling an adventitious pouch, such as a laryngocele, tracheocele, or gaseous swelling of the scrotum. Called also aerocele and pneumocele.
2. a usually benign, thin-walled, air-containing cyst of the lung, as in staphylococcal pneumonia. Called also pneumocele and pneumonocele.

1. An emphysematous or gaseous swelling.
2. Synonym(s): pneumonocele
3. A thin-walled cavity within the lung, one of the characteristic sequelae of staphylococcal pneumonia and Pneumocystis carinii pneumonia.

The incidence of pneumatocele formation secondary to RSV pneumonitis is unknown.
PLUS at least 2 serial chest radiographs showing new or progressive infiltrates, consolidation, cavitation or pneumatocele.
Among patients with pneumonia, 12 of 17 CA-MRSA were complicated (9 empyemas and 3 pneumatocele/pneumothorax) versus 2 of 13 CA-MSSA (1 empyema and 1 pneumatocele).
Other less common radiological findings include "crazy paving" pattern in the lung parenchyma; endobronchial secretions; or unspecific areas of post-obstructive pneumonitis, pneumatoceles, pneumomediastinum, pneumothorax, and pleural effusions [3-5].
In about 10% of patients, it can complicate with pneumatoceles, pneumothorax, and acute respiratory distress syndrome [1].
The presence of at least one of the following on one or more (in patients with underlying diseases two or more) serial chest radiographs, new or progressive radiographic infiltrates, consolidation, cavitation, and pneumatoceles in an infant [less than or equal to] 1 year old will also be needed for the diagnosis [6].
(2) Additionally, rupture of these blebs, apical cysts, and pneumatoceles may damage the visceral pleura causing a spontaneous secondary pneumothorax.
However, there are no skeletal or dental abnormalities, and no pneumatoceles. Rather, these patients suffer from severe viral (e.g., human papillomavirus, herpes simplex, varicella zoster, and molluscum contagiosum viruses) and opportunistic infections, asthma, and allergies.
Excluding patients who did not have a chest tube inserted because their disease was mild and those in whom fibrinolysis was contraindicated (22 pyopneumothorax, 9 pneumatoceles and 5 TB empyema), data on 99 patients from the pre- and post-fibrinolysis periods (TPA 52, no TPA 47) were available for comparative analysis (Fig.
However, pulmonary fibrosis and pneumatoceles were identified later.
In this case study, a 17 year-old male motor vehicle accident victim suffered severe trauma including bilateral lung contusions with pneumatoceles, several fractures to his femur, forearm, ribs, and thoracic vertebrae, plus splenic and liver lacerations.
