Voriconazole-induced Myositis in a Double Lung Transplant Recipient.

Voriconazole is a triazole antifungal agent commercially approved in 2002. It is commonly used in immunocompromised patients as a therapeutic and prophylactic agent. We present the case of a 26-year-old Caucasian female who is a double lung transplant recipient who presented with complaints of generalized left lower extremity swelling and extreme tenderness of her left thigh. Although her muscle enzymes were not significantly elevated, inflammatory changes were noticed on T2-weighted fat-suppressed short-TI inversion recovery (STIR) sequence magnetic resonance imaging (MRI). These findings were later confirmed with tissue biopsy. We hereby present the case of drug-induced myositis as a rare complication of voriconazole used as chemoprophylaxis in a double lung transplant recipient patient.
