title: [Cholangiocarcinoma in a patient with hepatosplenic atrophy subsequent to thorotrast administration (author's transl)].
abstract: A case of cholangiocarcinoma observed in a woman of 38 following carotidographic examination with Thorotrast is described: the presence of radioactivity was also demonstrated by gamma spectrometry. The high mean dose absorbed by the liver (estimated at about 3,000 rad) together with the high relative biological effectiveness of the alpha contribution and the time lapse justify the hypothesis that the neoplasia was caused by irradiation.
