Pneumatoceles in postpneumonic empyema: an algorithmic approach

Pulmonary Tuberculosis with Hematogenous Spread Associated with Hemaphagocytic Syndrome and Multiple Pulmonary Pneumatoceles

“…Pneumatoceles are usually associated with bacterial pneumonias (S. aureus, S. pneumoniae, H influenzae, Klebsiella, E. coli) [2,3], but they have also been described in P. jirovecci in HIV-infected patients 4 or caused by chest trauma. The association with TB disease is unusual and has seldom been described [4][5][6][7][8][9], even more rarely in childhood [10][11][12][13].…”

“…Usually, they resolve spontaneously, although it could be a slow process that lasts long after the resolution of primary process. In our case, we opted for a conservative management and radiological surveillance of pneumatoceles at the beginning, as the patient initially responded to antituberculous treatment and criteria for drainage aspiration or surgical treatment were not applicable in that moment (symptomatic patients or those with unstable situation, or in whom the size is not reduced or increases after starting appropriate treatment for a prolonged period of time, thickened wall, presence of bronchopulmonary fistula, or atelectasis pulmonary) [14].…”

Lung cysts following pulmonary artery operations: Diagnostic and therapeutic implications

“…As with post-pneumonic cysts these may ultimately resolve spontaneously 3,10 . The course towards the involution, may however, be punctuated by spontaneous rupture and pneumothorax, as seen in this case and should therefore be closely followed up clinically and radiologically to the point of complete resolution.…”

“…This mechanism, as in the case of pneumonias and poisoning leading to cysts is difficult to prove by direct methods. 3,5,[7][8][9] Chronology of events, lack of other precipitating causes, and the site of appearance of the cysts all point to a cause and effect relationship between the operation and the cyst formation. In this case the cysts were seen only after the second operation, there patient improved after drainage of the pneumothorax.…”

Neumonía complicada con neumatocele en un lactante, caso clínico

“…Esto es importante para el diagnóstico diferencial con neumotórax, que puede también presentarse en el curso de una neumonía. El neumatocele se observa como una lesión redondeada llena de aire, intraparenquimatosa, en contraste con el neumotórax, donde se observa colección de aire en el espacio pleural 3 . El neumatocele postinfeccioso generalmente aparece dentro de las primeras dos semanas de evolución de la neumonía.…”
