• The late effects of thorium dioxide (Thorotrast) in the perivascular space of the neck are reviewed. The roentgenographic analysis of the problem consists of both plain films (to detect the residual density of extravasated thorium dioxide) and computed tomography (to help define any involvement of the carotid artery).
