Mycotic aneurysm due to Magnusiomyces capitatus complicating a second liver transplant in a colonized patient

Year: 2024

Type: article

Abstract: This report presents an extremely rare case of a fungal mycotic aneurysm due to Magnusiomyces capitatus in a 51-year-old woman who is immunocompromised. The diagnosis was based on multiple computed tomography scans and the identification of the pathogen via sequencing of the internal transcribed spacer region. Long-term treatment with caspofungin for previous candidemia likely promoted the dissemination of this intrinsically echinocandin-resistant fungus from colonization sites in the lungs and rectal area. Long-term suppressive antifungal therapy with voriconazole and subsequently with posaconazole, combined with multiple surgical procedures, led to an improvement in the patient's condition. This case highlights the importance of considering a patient's comprehensive microbiological history and reassessing antimicrobial therapy in cases of nonimprovement or relapse.
