Candida utilis and Stenotrophomonas maltophilia co-infections connected to meningitis are uncommon. We describe a patient who developed C. utilis and S. maltophilia after undergoing neurosurgery and received effective nosocomial meningitis treatment. Multiple neurosurgeries were required for a 16-year-old girl due to complications. For probable nosocomial meningitis, she was treated with cefepime with vancomycin. Meropenem and liposomal amphotericin B were prescribed after her seizure and positive CSF culture for Candida utilis. Consequently, S. maltophilia was discovered in the CSF, and ceftazidime and trimethoprim-sulfamethoxazole were prescribed. The patient has been hemodynamically stable for the past two months, and consecutive CSF cultures have been negative. To the best of our knowledge, this is the first case of C. utilis and S. maltophilia co-infection that has been successfully handled.
