Diagnosis and treatment of a patient with pulmonary infection caused by Emergomyces Orientalis: a case report.

Emergomycosis is a dimorphic fungal disease that is typically disseminated and fatal among immunocompromised individuals. In the case report, we presented a patient with intermittent fever, night sweats, coughing and phlegm. Chest computed tomography revealed multiple soft-tissue nodules in both lungs. Routine pathological and microbiological tests did not confirm the diagnosis. Therefore, we conducted pathogen detection using metagenomic next-generation sequencing in bronchoalveolar lavage fluid and identified the pulmonary infection caused by Emergomyces orientalis (Es. orientalis). During the antifungal treatment, the patient experienced renal function damage, and we have attempted various antifungal drugs for treatment. Finally, the patient's condition was brought under control. Therefore, the metagenomic next-generation sequencing pathogen detection was essential.
