Scintigraphic evaluation of reduced-size liver transplant from living related donor in Byler's disease.

Byler's syndrome is a rare form of autosomal recessive intrahepatic cholestasis that is fatal in children. A 10-year-old girl diagnosed with Byler's syndrome underwent reduced-size liver transplantation using lateral segments of her living mother's liver. The donor's and the recipient's liver functions after transplantation were evaluated using Tc-99m disofenin and Tc-99m SC to investigate morphology, liver perfusion, and hepatobiliary function.
