title: A hepatobiliary study with Tc-99m N-pyridoxyl-5-methyltryptophan (PMT) in a patient with hepatoblastoma.
abstract: A patient with hepatoblastoma in whom a hepatobiliary study with Tc-99m PMT demonstrated homogeneous uptake in the tumor is presented. Sonography showed a large solid mass pedunculated from the right hepatic lobe with a "tumor-in-tumor" pattern. It was hypodense relative to normal hepatic parenchyma on CT scanning without contrast material and turned isodense with contrast material. This represented its hypervascularity, which was confirmed by selective celiac arteriography.
