The lung mass was most concerning for malignancy, and positron emission tomography (PET) further supported this concern, with intense uptake in the mass as well as in mediastinal and hilar lymph nodes. Biopsies however were non-diagnostic, and the patient developed acute kidney injury with active urinary sediment, leading to a definitive diagnosis of GPA. With supportive care and treatment directed at GPA, she was ultimately able to discontinue hemodialysis, and the lung mass resolved. This case …
