Fatal post-operative Trichoderma longibrachiatum mediastinitis and peritonitis in a paediatric patient with complex congenital cardiac disease on peritoneal dialysis.

Trichoderma longibrachiatum is an emerging pathogen in immunocompromised patients. We report a case of Trichoderma post-operative mediastinitis and peritonitis in a child with complex congenital cardiac disease and functional asplenia. The patient was treated unsuccessfully, initially with caspofungin alone followed by a combination of voriconazole (systemic and topical), caspofungin and intraperitoneal amphotericin B.
