Pneumatocele

Classification according to ICD-10
G93.88	Intracranial pneumatocele
J98.4	Other changes in the lungs - pneumatocele
ICD-10 online (WHO version 2019)

A pneumatocele (from ancient Greek πνεῦμα pneuma , German 'breath, wind' and ancient Greek κήλη kele , German 'break' ) or pneumocele generally refers to a pathological accumulation of air in tissues in the sense of an air-containing pseudocyst .

In particular, a protrusion of lung tissue due to a defect in the chest wall, a so-called lung prolapse , is referred to as a pneumatocele.

Occurrence

As a rule, a pneumatocele is a change in the

the lungs
the paranasal sinuses , so-called pneumosinus dilatans
the base of the skull after non-surgically treated frontobasal fractures

However, there have been case reports of less common locations such as the scrotum (pneumoscrotum), in the bones or the lacrimal sac .

Chest x-ray with a large pneumatocele in the right lower lobe, ventilated premature baby with respiratory distress syndrome in the newborn and grafted RSV pneumonia.

Pulmonary pneumatocele

Possible causes are:

Pneumonia , often from staphylococci
Abscessing Pneumonia
Trauma with parenchymal tear , not infrequently as a complication of ventilation in premature infants
Aspiration of hydrocarbons
Aspiration of oil or fats

diagnosis

The diagnosis results from the X-ray image , on which a sharply delimited circumscribed air equivalent brightening becomes visible. An overview image is sufficient for the lungs, while computed tomography is necessary for the base of the skull .

Differential diagnosis

To be distinguished are (mucus-filled) cysts in cystic fibrosis , cystic echinococcosis and congenital lung changes ( cystic adenomatoid malformation of the lungs ).

Prospect of healing

The prognosis is generally good, as the pulmonary pneumatoceles regress within 2-3 months. An exception is when the cyst is connected to the bronchial system with a valve mechanism . Then surgery is required.
