Neosartorya udagawae pulmonary infection requiring a surgical treatment in a paediatric haematopoietic progenitor cell recipient

Abstract

Neosartorya udagawae is a known cause of fungal infection in humans and animals. It is found to be more refractory to antifungal treatment in comparison to other Aspergillus species. With this report we present a case of proven invasive infection with Neosartorya udagawae in a child with chronic myeloid leukaemia after haematopoietic stem cell transplant. The patient received several lines of antifungal therapy including dual therapy appropriate to the antifungal susceptibility profile with progression of the invasive fungal disease requiring left lung upper lobe lobectomy. The case emphasizes the importance of early biopsy with antifungal susceptibility testing for targeted therapy and demonstrates the potential requirement for surgical management in addition to appropriate antifungal treatment.
