A 32-year-old man was admitted to our institution with prolonged fever, bilateral episcleritis, hearing loss, fatigue, and weight loss. A chest radiogram showed pulmonary infiltrates that were interpreted as bacterial pneumonia but did not improve with antibiotics. Initial blood test investigations revealed elevated levels of C-reactive protein (13.59 mg/dL; range, 0.01-0.9 mg/dL [to convert to nanomoles per liter, multiply by 9.524]) with a white blood cell count of 16 700 cells/μL (range, 4000-11 000 cells/μL) with 79% of neutrophils.
