Thorotrast induced adhesive arachnoiditis associated with meningioma and schwannoma.
Adhesive arachnoiditis, a meningioma and a schwannoma were found at autopsy in a 56 year old man who had undergone Thorotrast myelography 33 years previously. Thorotrast was demonstrated in tissue sections by transmission and scanning electron microscopy, radioautography, and x-ray spectrometry.
