Objective: Voriconazole is an antifungal medication used primarily for the treatment of Candida and Aspergillus infections. A fairly newly described side effect of long-term voriconazole use is periostitis. The purpose of this article is to describe the main differential consideration-hypertrophic osteoarthropathy-and other differential diagnoses, including venous stasis, thyroid acropachy, and hypervitaminosis A.
Conclusion: With knowledge of imaging appearance, clinical manifestations, and outcomes, radiologists can make an accurate diagnosis of voriconazole-induced periostitis, and clinical teams can initiate appropriate management.
