Clinical and Imaging Findings in 18 Patients with Eosinophilic Pneumonia

Background/Objective: Eosinophilic pneumonia is a rare cause of lung disease in adulthood. The relatively non-specific clinical presentations of this disease process make the diagnosis a unique challenge. Herein, we reported on clinical and radiological manifestations of this rare clinical entity in 18 patients. "nPatients and Methods: We retrospectively reviewed the medical records of 18 patients with acute eosinophilic pneumonia in Masih Daneshvari Medical Center. Diagnostic criteria were based on clinical, laboratory and imaging findings."nResults: The most clinical manifestations were cough and weight loss 15 (0.83) followed by dyspnea 13 (0.72). The most frequent imaging findings were diffuse opacities (reticulo-nodular or alveolar infiltration) in 11 (0.65), consolidation in six (0.33) and ground-glass opacities in four (0.28) patients."nConclusion: Diffuse rather than peripheral air-space opacities in imaging of a patient presented with dyspnea, cough, sputum, constitu-tional symptoms and eosinophilia should make us to think about eosinophilic pneumonia as one of differential diagnoses.
