Abstract
OBJECTIVES: A 61-year-old with acute granulomatosis and polyangiitis developed Aspergillus fumigatus pneumonia after admission to the intensive care unit with a small bowel perforation. This occurred after immunosuppression (intravenous methylprednisolone, intravenous cyclophosphamide, and plasmapheresis) for his initial presentation with stage 3 acute kidney injury. MATERIALS AND METHODS: The mycologist recommended long-term treatment with voriconazole after initial recovery. RESULTS: After 7 months of treatment, the patient complained of joint pain and swelling in his hands. Radiographs, computed tomography, and single-photon emission computed tomography appearances were consistent with periostitis. A diagnosis of Voriconazole-induced periostitis deformans was made and the voriconazole was stopped. Plasma fluoride level was 278 μg/L (normal range < 50 μg/L). Discontinuation of voriconazole led to clinical improvement. CONCLUSIONS: Periostitis deformans due to fluorosis is a rare complication of voriconazole treatment. The imaging in our case is unusually dramatic. We were able to track the evolution of periosteal reactions over serial imaging.
