title: Gliosarcoma developing in close relationship to an abscess cavity injected with thorotrast.
abstract: A case of an unusual tumor developing at the site of an abscess is reported. The tumor presented 21 years after burr hole drainage of the abscess and instillation of the contrast medium thorotrast. The bizarre nature of the tumor and its immediate proximity to the thorotrast lead the authors to believe that the tumor was caused by the contrast medium.
