these terms are some times used synonymously
it's just tht pneumonia is reserved for infections but pneumonitis is reserved for mainly inanimate objects like different environmental and occupational pullutants resonsible for restrictive diseases such as silicon,asbestos but ofcourse it also includes some infectius causes as well like PCP
don't get so confused with these terminologies ,borads certainly won't be testing concrete differences b/w such terms!

So an aspiration pneumonia is an unproper term to use? Say if you aspiration stomach content? It should be aspiration pneumonitis?

I don't think that aspiration pneumonia would be in unproper term to use, cause you might end up with anaerobic bacteria causing trouble, which is why you would add metronidazole to the medication.

Pneumonia is a condition where there is an excessive amount of pus is produced and is a collection of neutrophils. The peptidoglycan and the teichoic acid parts of the cell wall of the bacteria are highly chemotactic factors for neutrophils. The organism is extracellular.
Pneumonitis on the other hand is a condition where there is no pus produced. It can be caused by anything that is infact intracellular in nature, meaning which is phagocytosed by the macrophages and the macrophages inturn secrete the interleukins which brings the lymphos and the fibroblasts in action. So the agent can be a microbe that resides intracellularly or any inorganic substance like asbestos, silica etc.
Another thing, in pneumonia the neutrophilic infiltrate is actually present in the alveolar cavity in pneumonitis the infiltrate is a interstitial in nature, that means its not present in alveolar cavity, but in the alveolar walls.
