A 54-Year-Old Woman With Rheumatoid Arthritis, Low-Grade Fever, and Cough

A 54-year-old Indian woman presented with low-grade fever and cough with expectoration for 1 month. Fever was not associated with any chills or night sweats. Expectoration was minimal in amount and mucoid in nature. Her appetite was decreased, without any significant weight loss. She denied any history of dyspnea or hemoptysis. The patient was diagnosed with rheumatoid arthritis 1 year previously and was initially started on methotrexate and short-term glucocorticoids. At the time of presentation, she was taking methotrexate 15 mg weekly and hydroxychloroquine 200 mg daily. Her joint disease was controlled on immunomodulators. She had no other comorbid condition, and she was a never smoker. She neither traveled within or outside India in the past nor came in contact with patients with pulmonary TB. A chest radiograph was done because a prior workup showed an ill-defined solitary nodular lesion in the right lower zone. She took a course of amoxicillin-clavulanate, but that was of no benefit.
