Diagnostic Considerations

Aspiration frequently occurs in the setting of altered consciousness. Neurogenic pulmonary edema (NPE) tends to develop more rapidly than aspiration pneumonia. Although neurogenic pulmonary edema does not cause fever, the neurological insults that result in neurogenic pulmonary edema (eg, subarachnoid hemorrhage) may be associated with fever. Aspiration pneumonia may take 1-2 weeks to resolve, whereas neurogenic pulmonary edema resolves within hours to several days. [9]
