Visualization of the liver with 99mTc-EHDP in thalassemia major.

A case is reported in which substantial liver uptake of 99mTc-hydroxyethylidene diphosphonate (99mTC-EHDP) was seen on bone scan. The patient, a 25-year-old male with the diagnosis of thalassemia major made at the age of 3 years, had received regular blood transfusions over many years. Clinical and laboratory evidence of hemosiderosis suggests that the presence of large quantities of iron in the liver of this patient may have been responsible for the hepatic uptake of the bone scanning agent.
