Brain Abscess Caused By "Corn Smut" Ustilago Species In An Immunocompetent Child

Ustilago species is a pathogenic fungus that causes a fungal corn disease called "corn smut". Airborne-spores may cause hypersensitivity pneumonitis in humans with atopy. It has been identified as a rare pathogen in central line blood infections in immunocompromised patients. Ustilago has not been reported as a cause of brain abscess in an immunocompetent person. We report a case of multifocal brain abscesses in a previously healthy immunocompetent boy caused by Ustilago sp. Excision biopsy established the diagnosis. The child fully recovered without any residual neurological defects.
