Detection of a 2.1 cm hepatocellular carcinoma in an 11-year-old boy by Tl-201 chloride. Case presentation and correlative imaging findings

Abnormal uptake of Tl-201 chloride in the liver along with correlative radiologic imaging is presented in an unusual case of an 11-year-old boy with a small 2.1 cm hepatocellular carcinoma. Although planar Tl-201 images were normal, triple-headed SPECT Tl-201 images showed a focal area of increased liver activity at the site of the tumor which corresponded to a photopenic area on Tc-99m SC SPECT images. The patient successfully underwent partial liver resection of a pathologically proven hepatocellular carcinoma.
