Q
CHEST
A Computed tomography (CT) chest is done in a 6-month-old girl with a history ofpremature birth, chronic lung disease and MRSA pneumonia. It shows a large gas-containing,thin-walled cavity in the right lung, consistent with a pneumatocele. All the following aretrue regarding a pneumatocoele, except:
A. They are gas-filled, thin-walled spaces surrounded by lung.
B. They can be associated with lung contusion.
C. Most pneumatocoeles resolve spontaneously.
D. Pneumatocoeles do not cause mediastinal shift.
E. They can have fluid levels.
A
D. Pneumatocoeles do not cause mediastinal shift.
Pneumatocoeles typically are post-infectious or post-traumatic, discrete, thin-walled,gas-containing collections within the lung parenchyma. They also may result from positive pressure ventilation-related barotrauma and ingestion of caustic material (e.g. hydrocarbons). Post-infectious pneumatocoeles most frequently complicate staphylococcal pneumonia and occur in infants. They typically appear within 1 week of onset of infection and most spontaneously disappear within weeks to months after the infection has resolved. Rarely, persistent pneumatocoeles may require percutaneous catheter drainage or surgical management. Post-traumatic pneumatocoeles result from blunt trauma. Such pneumatocoeles are typically observed within hours of the trauma and spontaneously resolve within 3 weeks. They generally spare the lung apices.
At CT, pneumatocoeles appear as well-defined parenchymal cystic structures, with a thin wall. They may be entirely filled with gas, or an air-fluid level may be seen. Contralateral mediastinal shift may be seen with large pneumatocoeles. They are associated with contusion in blunt trauma and can rupture to cause pneumothorax.
