Aspergillus flavus as a cause of thyroiditis in an immunosuppressed host

Disseminated aspergillosis is a major complication in immunosuprressed patients. Infiltration of the thyroid with Aspergillus organisms occurs in approximately 20% of autopsies in patients dying with disseminated disease. The present report describes Aspergillus thyroiditis, Hashimoto's thyroiditis, and possible hypothyroidism in a patient with disseminated aspergillosis.
