title: CT appearance of abdominal thorotrast deposition and Thorotrast-induced angiosarcoma of the liver.
abstract: Although the clinical and radiographic manifestations of Thorotrast and its complications have been described, the computed tomographic (CT) appearance of Thorotrast deposition in the abdomen is less well known. Thorotrast produces a characteristic opacification of the liver, spleen, and abdominal lymph nodes. We report two cases of patients with Thorotrast-induced angiosarcoma of the liver detected by CT. Computed tomography in both cases demonstrated space-occupying lesions in the liver, which were readily detectable because of distortion of the Thorotrast-produced opacification.
