Thyrotoxicosis Induced by Thyroid Involvement of Disseminated Aspergillus fumigatus Infection

Aspergillus fumigatus is increasingly recognized as an important nosocomial pathogen in severely immunocompromised patients. Infection is difficult to diagnose antemortem and typically has a fatal outcome. Here we report the case of a cardiac transplant recipient with disseminated A. fumigatus infection which clinically presented as thyrotoxicosis due to massive involvement of the thyroid gland.
