Acute Eosinophilic Pneumonia Associated With COVID-19 Infection

The knowledge about COVID-19 infection and sequelae is evolving. Acute eosinophilic pneumonia (AEP) is not a well-recognized complication of COVID-19 infection, with few cases reported in the literature. We report a case of a 60-year-old male with a history of an orthotopic heart transplant on chronic immunosuppression who had AEP three weeks after a COVID-19 infection. He presented with diarrhea and acute kidney injury without respiratory symptoms. After discharge, the patient experienced progressive fevers, dyspnea, and cough resulting in a second admission to the hospital with acute hypoxic respiratory failure requiring supplemental oxygen. Imaging demonstrated ground-glass opacities with areas of consolidation and bronchoalveolar lavage fluid demonstrated AEP. The patient was treated with steroids resulting in the resolution of his symptoms and radiographic findings. This case highlights the potential for AEP to complicate COVID-19 infections.
