Résumé : A liver transplant recipient developed infection of a perihepatic haematoma due to Trichoderma viride. Before the infection was diagnosed, the patient received intense immunosuppressive and prolonged antibacterial and antifungal therapies. Although the death of the patient was not directly related to the fungal infection, abundant quantities of this pathogen were recovered in the haematoma at post-mortem examination, despite previous surgical removal and treatment with amphotericin B and fluconazole.
