title: Tl-201 positive, Ga-67 negative hepatoblastoma: a case report of a 12-year-old boy.
abstract: Hepatoblastoma is a primary liver neoplasm in which prompt diagnosis and resection are critical to long-term survival. Nuclear scintigraphy plays an important role in the characterization of hepatic masses. The authors present an unusual case of hepatoblastoma in a 12-year-old boy in whom Ga-67 scintigraphy and serum alpha-fetoprotein were negative. Positive Tl-201 scintigraphy pointed toward the true malignant nature of the mass and should be considered in the investigation of hepatic masses in childhood.
