Cryptococcus magnus Periprosthetic Shoulder Infection: A Case Report.

CASE: We present a 68-year-old diabetic man with a periprosthetic shoulder infection (PSI) by Cryptococcus magnus. The fungus was identified 4 weeks after a revision surgery for a chronic bacterial PSI. Treatment was successful with a 2-week course of intravenous liposomal amphotericin B (5 mg/kg) followed by 6 weeks of fluconazole (200 mg/d).

CONCLUSION

To the best of our knowledge, only 2 periprosthetic infections due to Cryptococcus neoformans have been previously reported. This is the first report of cryptococcal involvement of a prosthetic shoulder, and the first identified osteoarticular infection ever by C. magnus.
