Thorotrast-induced meningioma. Case report.
The authors report an adult patient with a symptomatic intracranial meningioma that was demonstrated by computerized tomography, angiography, and at surgery. The meningioma had occurred at a site where 19 years previously thorium dioxide had been injected into an abscess cavity. Pathological examination revealed the presence of thorium granules within the meningioma.
