Abdominal pain: do not forget Thorotrast!
The use of Thorotrast (25% thorium dioxide), a radiologic contrast agent used up until the mid-1950s, was associated with a wide range of malignancies, mainly of hepatic origin. We report a case of Thorotrast-induced hepatocarcinoma in an 82-year-old woman.
متن کاملIdentification of thorium dioxide in human liver cells by electron microscopic x-ray microanalysis.
Thirty-two years after injection of thorium dioxide (Thorotrast) for diagnostic x-ray studies in a female patient deposits were found by light microscopy in the liver macrophages (Kupffer cells). They were shown by electron microscopy to be located inside secondary lysosomes, and by autoradiography and x-ray microanalysis they were identified as thorium.
متن کاملThe Effectiveness of Colloidal Thorium Dioxide as an Internal Alpha Emitter: A Combined Morphologic and Radioautographic Study ‡
The hazard of ionizing radiation from internally administered colloidal thorium dioxide (Thorotrast) has been a subject of controversy even since this medium was first employed in clinical roentgenology. Reports of neoplasia as well as diffuse hepatic fibrosis occurring in patients following Thorotrast administration have been summarized and evaluated by Thomas et al.7 Although intravenous inje...
متن کاملCT recognition of thorotrast-induced intracranial and lumbar arachnoiditis.
In the 1930s and 1940s the radioactive contrast material colloidal thorium dioxide (Thorotrast) was frequently used in radiographic examinations. The agent was used mainly for angiography and to a lesser extent for myelography, ventriculography, pyelography, and hepatolienography. The late clinical complications and conventional radiographic manifestations of thorium administration have been we...
متن کاملRecognition and Clinical Importance of Thorium Dioxide (Thorotrast®) Deposits in Human Unstained Bone Marrow Smears
Direct microscopic estimation of the amount of hemosiderin in an unstained bone marrow smear is of great value in the clinical evaluation of iron deficiency and iron excess.' Usually, the highly refractile golden or amber crystals of hemosiderin are easily identified and need be differentiated only from particulate artifacts in the unstained marrow preparation. In the course of evaluating sever...
