what is a rare form of pneumonia

Eosinophilic pneumonia is a rare form of pneumonia that affects the lungs. It is caused by a type of white blood cell called eosinophils building up in the lungs and blood, causing inflammation and damage. There are three main types of eosinophilic pneumonia: acute eosinophilic pneumonia (AEP), chronic eosinophilic pneumonia (CEP), and simple pulmonary eosinophilia (SPE) . AEP is a rare disorder characterized by the rapid accumulation of eosinophils in the lungs, while CEP is a rare disorder characterized by the massive accumulation of eosinophils in the lungs. SPE is a mild form of eosinophilic pneumonia that usually resolves on its own. Symptoms of eosinophilic pneumonia can resemble those of common viral illnesses and respiratory conditions, making it challenging to accurately diagnose. Diagnosis typically involves a chest x-ray, computed tomography, bronchoscopy, and blood tests to measure the number of eosinophils. Treatment may involve medications to ease symptoms and prevent respiratory failure.
