Cavitating pneumonia
Updates to Article Attributes
A cavitatingCavitating pneumonia is a complication that can occur with with a severe necrotising pneumonia and in some publications it is used synonymously with the latter term 2. It is a rare complication in both children and adults.
Cavitation associated Mycobacterium tuberculosis is separately discussed in the pulmonary tuberculosis article.
Pathology
CavitatingCavitation can occur from a variety of organisms.
Paediatric population
Albeit rare, cavitation is most commonly caused by Streptococcus pneumoniae which other less frequently being Aspergillus spp., Legionella spp.and Staphylococcus aureus 4.
In children cavitation associated with severe illness although cases usually resolve without surgical intervention, and long-term follow-up radiography shows clear lungs without pulmonary sequelae 1,6.
Adult population
Although the absolute cavitatorycavitary rate may not be known, according to one series, necrotising changes were seen in uptoup to 6.6% of of adults with pneumococcal pneumonia 7. Kleibsiella pneumoniae is also another organisumorganism that is known to cause cavitation 8.
Radiographic features
Plain film
May show a subtle area of radiolucency superimposed on a region of consolidation.
Late sequelae
- pneumatocoele formation
- lung abscess formation
