Cavitatory pneumonia
Cavitating pneumonia is a complication that can occur with severe necrotizing pneumonia and in some publications, it is used synonymously with the latter term . It is a rare complication in both children and adults.
Cavitation associated with Mycobacterium tuberculosis is separately discussed in the pulmonary tuberculosis article.
Pathology
Cavitation can occur from a variety of organisms.
Pediatric population
Albeit rare, cavitation is most commonly caused by Streptococcus pneumoniae, and less frequently Aspergillus spp., Legionella spp. and Staphylococcus aureus .
In children, cavitation is associated with severe illness, although cases usually resolve without surgical intervention, and long-term follow-up radiography shows clear lungs without pulmonary sequelae .
Adult population
Although the absolute cavitary rate may not be known, according to one series, necrotizing changes were seen in up to 6.6% of adults with pneumococcal pneumonia . Klebsiella pneumoniae is another organism that is known to cause cavitation .
Radiographic features
Plain radiograph
May show a subtle area of radiolucency superimposed on a region of consolidation.
Late sequelae
- pneumatocele formation
- lung abscess formation
