Voriconazole-induced periostitis (VIP) is an uncommon side effect typically seen in immunosuppressed patients requiring prolonged antifungal therapy. These patients can present with bone pain, fragility, and elevated alkaline phosphatase (ALP). We present a case of VIP in a 72-year-old immunocompromised female on antifungal therapy presenting with a comminuted intertrochanteric fracture after a ground-level fall. VIP, although rare, should be included as a differential diagnosis for patients presenting with bone pain and/or fractures with radiographic features of periostitis. This is particularly true when there is a history of or prior imaging suggesting a solid organ transplant. In these cases, a dedicated review of current medications noting long-term voriconazole use in the absence of underlying rheumatologic disease can result in a confident diagnosis.
