A 40-year-old woman presented to the pulmonary clinic with abnormal chest radiograph findings. She had longstanding primary Raynaud phenomenon, and 3 years prior to this presentation she had experienced transient, right knee inflammatory arthritis of unclear etiology. One month prior to the clinic visit, bilateral knee and wrist arthralgias developed with subjective fevers; the patient presented to her primary care doctor with these complaints. In retrospect, her 4-year-old son had experienced fevers and a rash, and had been subsequently diagnosed with Fifth disease. Her physician was concerned about sarcoidosis and obtained a chest radiograph. Based on these results, a chest CT scan was performed, and the patient was referred to the pulmonary clinic for further evaluation.
