Pneumonia vs. Pneumonitis

Although the names are nearly identical, pneumonitis is not the same as pneumonia. Pneumonitis is lung inflammation without infection, whereas pneumonia is lung inflammation that results from infection. In addition, pneumonia is generally limited to one or two areas of the lungs, but pneumonitis involves all five lobes — two in the left lung and three in the right.
