Initially presenting with rhinorrhea and nasal obstruction, the patient was diagnosed with AFRS in the right maxillary sinus, followed by a postoperative course of CGIFS in the left nasal cavity, showcasing the unique occurrence. She was not immunocompromised during diagnosis. CGIFS may have occurred because of surgery; however, voriconazole led to significant improvement. This case highlights noninvasive and invasive fungal infections in patients with chronic rhinosinusitis and a history of GVHD and underscores the complexity of diagnosing and managing such cases.
