Patient Presentation

A middle-aged woman presents with 2-3 weeks of mild but progressive shortness of breath with exertion associated with low-grade fevers, worsening night sweats, and fatigue. Further history reveals a progressive non-productive cough and weight loss. She has a past medical history of neurologic dysfunction over two years and a working diagnosis of chronic inflammatory demyelinating polyneuropathy and is pursuing treatment in Mexico due to cost limitations. She has been receiving prednisone 10 mg daily and azathioprine. Aside from travel history to Mexico, her social history is notable for prior employment in a candle factory, and for hiking with some cave exploration. She is a former 20 pack-year smoker and has rare alcohol use.
