In bronchogenic carcinoma you are more likely to see a discrete mass, with atelectasis/collapse distally.
The most common types are squamous cell carcinoma (30-40%) and adenocarcinoma (also 30-40%). Squamous cell is more likely to be a central discrete lesion with cavitation, while adenocarcinoma is more often peripheral and almost never cavitates.1
In pneumonia (lobar) you may see more diffuse consolidation throughout the lobe +/- some collapse.

The difference between "walking pneumonia" and "true pneumonia".
Pneumonia involves the swelling or inflammation lung tissue and it is infectious whereas pneumonitis is not infectious.
i myself have had walking pneumonia and it is the same infection but with walking pneumonia you don't really feel all that ill. you caould just feel as though you have a cold and you can be walking around and carrying on as normal without knowing you had it. this doesn't mke it any less serious though.
Pneumonia is one type of lung infection, but not all infections are pneumonia. It depends on which sort of bacteria are causing the infection and where in the lungs the infection is.
Bronchitis often has a colored flam while allergies are clear.

Atelectasis is the collapsing of a lungwhen there is an interference with the natural forces that promote lung expansion. Pneumonia is an inflammatory process and infection, usually involving fluid in the lungs.Atelectasis is basically a collapsed lung.
You have 3 lobes on the right side and 2 lobes on the left (with a little bitty middle lobe in between on the left). When you have left lower lobe pneumonia it is at the base of your left lung. When you have bilateral pneumonia it is on both sides of the chest (right and left lungs), but it could be in any lobes(most commonly at the bases).
Pneumonia is a general term, not a specific disease. There is viral pneumonia, bacterial pneumonia, and a fungal pneumonia, among others.

There is no opposite of pneumonia.
