Scintiangiography of hepatic masses in childhood

G. F. Gates, J. H. Miller and P. Stanley

Forty-three children with intrahepatic masses had technetium Tc 99m sulfur colloid hepatic scintigrams including scintiangiography. Hypervascularity occurred in nearly one third of the masses, but was limited to children with primary liver tumors including hepatomas, hepatoblastomas, hepatic adenomas, and cavernous hemangiomas. All metastases, abscesses, and hematomas were hypovascular. Routine inclusion of scintiangiography may allow separation of primary hypervascular liver tumors from other hypovascular masses whose static hepatic scintigrams are virtually identical.
