Pneumatocele is most often seen in children with bacterial pneumonia but also develops after blunt thoracic trauma, positive pressure ventilation, and caustic aspiration. We here describe a case of pulmonary pneumatocele in postpneumonic empyema in a child.Generally pneumatocele need not an interventional treatment and an excellent prognosis can be given with only surveillance and antibiotic if...

Pneumatocele formation is a known complication of pneumonia. Very rarely, they may increase markedly in size, causing cardiorespiratory compromise. Many organisms have been implicated in the pathogenesis of this disease; however, this is the first report of tension pneumatocele resulting from Enterobacter gergoviae pneumonia. We report a case of a 3-month-old Nigerian male child who developed t...

Community-acquired bacterial pneumonias generally have a good prognosis, given a good response to the antibiotic treatment applied, and complications such as pleural effusion, empyema, abscess and necrotizing pneumonia with pneumatocele formation (cavitary necrosis) are rare. Although cavitary necrosis is manifested as a severe disease, most children show complete recovery even without surgical...

Characteristic lesions of staphylococcal pneumonia in infancy are the tension cyst of lung and tension pyopneumothorax. The radiological appearances are often alarming and, at first sight, seem to indicate the necessity for urgent aspiration or drainage. The two obvious dangers are those of immediate suffocation (the French refer to the tension cysts as bulles suffocantes) and of gross pleural ...

The entrapment of intracranial air from the check valve system results in a tension pneumatocele. Tension pneumatoceles should be distinguished from simple pneumatoceles because they are intracranial space-occupying masses that can threaten life. Head trauma is one of the causes in etiopathogenesis of Parkinson’s disease. Here, we describe a case of a 50-year-old man who developed Parkinson’s d...

Systemic air embolism is known to rarely complicate blunt chest trauma. However, cerebral infarction caused by air emboli possibly originating from a traumatic pneumatocele has not been previously reported. We report a case of a 46-year-old woman who sustained blunt chest trauma with multiple rib and clavicular fractures, hemothorax and a huge, tense traumatic pneumatocele. She subsequently dev...

Pneumatocele formation is unusual in adult pneumonia, particularly in pneumococcal pneumonia. We report three cases of pneumatocele formation in adults, including one with probable pneumococcal pneumonia. All three patients were severely ill and two expired. Although they are usually asymptomatic, pneumatoceles may enlarge and compress the adjacent lung and mediastinum. This occurred in two pat...

Pulmonary pneumatoceles are air-filled thin-walled spaces within the lung and are rare in adult cases of pneumonia. We report the case of a 74-year-old male who was admitted with a cough and sputum production. He had been treated with oral dexamethasone since a brain tumorectomy 6 months prior. Contrast-enhanced computed tomography (CT) of the chest revealed a large pneumatocele in the right mi...

We report a case of an infected pneumatocele in the course of anaerobic pneumonia in an adult. To the best of our knowledge, anaerobic pneumonia complicated by a pneumatocele in an adult has not previously been described. The pneumatocele occurred on the fifth day of hospitalization, and rapidly increased in size, with the development of a subsequent mixed anaerobe infection. A pig-tail cathete...
