Muscle pain, fever, cough, and progressive dyspnea in a woman with eosinophilic pneumonia

The diagnosis of eosinophilic pneumonia (EP) is rare and challenging. This condition is frequently misdiagnosed as pulmonary tuberculosis, lymphoma, schistosomiasis, Wegener’s granuloma, severe acute respiratory syndrome, or severe community-acquired pneumonia. Herein, we report a case in which computed tomography (CT)-guided percutaneous lung biopsy was used to diagnose EP without alveolar eosinophilia or peripheral eosinophilia. A roundworm identified in the patient’s stool confirmed the precise diagnosis to be parasitic EP. This is, to our knowledge, the first reported case of EP confirmed by CT-guided percutaneous lung biopsy. CT-guided percutaneous lung biopsy may represent a new tool for the diagnosis of EP in patients without typical alveolar eosinophilia or peripheral eosinophilia.
