A 37-year-old previously healthy and athletic woman presented to the ED in October 2018 with acute-onset high fever, dyspnea, and productive cough. Chest radiograph showed bilateral infiltrates that correlated with multifocal ground glass opacities in a thoracic CT scan (Fig 1). The patient was severely hypoxemic and required intensive care and oxygen administration via a high-flow nasal cannula. ⋯ Immunoglobulins that included IgG1-4 and IgA and renal function were normal. Sicca symptoms like xerophthalmia and xerostomia were negated. The patient fully recovered after empiric administration of antibiotics and glucocorticoids (initially 500 mg methylprednisolone daily over 3 days with consecutive tapering).

Empiric antibiotic was started, with no improvement. Chest radiograph was performed, which showed bilateral nodular opacities (Fig 1). ⋯ She was a nonsmoker. She worked in an office setting and denied any occupational or recreational exposures or recent travels. There was no family history of lung diseases or cancer.
