Mondo Description An inflammatory lung disorder characterized by an increased number of eosinophils in the lungs. The majority of cases are idiopathic, without identifiable cause. In a minority of cases, medications, fungal infections, and environmental triggers have been implicated. It manifests as acute or chronic. Acute eosinophilic pneumonia is a severe and rapidly progressing pneumonia that may lead to respiratory failure requiring mechanical ventilation. Chronic eosinophilic pneumonia follows a slower course and manifests as fever, dyspnea, cough, and weight loss.

Disease Ontology Description A pneumonia in which certain type of white blood cell called an eosinophil accumulates in the lung. These cells cause disruption of the normal air spaces (alveoli) where oxygen is extracted from the atmosphere. It is caused by certain medications or environmental triggers, parasitic infections, and cancer. The most common symptoms include cough, fever, difficulty breathing, and sweating at night.
