FATAL ABDOMINAL THOROTRAST GRANULOMA

We report a case of fatal abdominal thorotrast granuloma seen in a 65-year-old man who had undergone a femoral angiography of thorotrast with some accidental extravasation 49 years previously. As the thorotrast granuloma gradually increased in size, it caused ureteral obstruction, venous thrombosis, and perforation of the urinary bladder and rectum. Symptomatic abdominal thorotrast granuloma is quite rare and this is the first reported case of the granuloma associated with perforation through the urinary bladder and rectum.(Internal Medicine 31 : 1220-1223, 1992)
