Chronic eosinophilic pneumonia usually follows a slower course.

Treatment When eosinophilic pneumonia is related to an illness such as cancer or parasitic infection, treatment of the underlying cause is effective in resolving the lung disease.

Several different kinds of eosinophilic pneumonia exist and can occur in any age group.

CEP occurs more frequently in women than men and does not appear to be related to smoking.

There is some suspicion that at least AEP is the result of the body's response to some unidentified environmental agent.

The final group of parasites cause EP when a large number of eggs are carried into the lungs by the bloodstream.

In CEP, treatment is usually continued for three months after symptoms disappear and the x ray returns to normal (usually four months total).

AEP can occur at any age, even in previously healthy children, though most patients are between 20 and 40 years of age.

So if a radiologist is looking at the scan of a patient with suspected pneumonia, say, what happens is that, if they see evidence of pneumonia on the scan, they literally stop looking at it thereby missing the tumor sitting three inches below on the patient's lungs.
