[Pulmonary Infiltrate - Not Always Due to Bacterial Infection]

Pulmonary Infiltrate - Not Always Due to Bacterial Infection Abstract. A 65-year-old female patient with a history of controlled asthma was diagnosed with community-acquired pneumonia (CAP). After two weeks of treatment on co-amoxicillin, she failed to respond and was referred for further investigations. Clinical symptoms and laboratory results were suggestive for eosinophilic granulomatosis with polyangiitis (EGPA). Diagnosis and treatment of this disease are still challenging, especially in cases with vital organ involvement.
