Abstract

A 74-year-old woman sought treatment with a 4-day history of high fever and rapidly progressive dyspnea. A 2-day course of ceftriaxone and betamethasone administered in an outpatient setting did not result in any clinical improvement, leading to her admission to our hospital. She demonstrated a slight cough but did not report heartburn, night sweats, hemoptysis, myalgia, arthralgia, or weight loss. Her family history was unremarkable.
