Detection of metastatic lesions by bone scintigraphy is highly sensitive but has a low rate of specificity. Often
bone metastases
from hepatocellular carcinoma are not detected by bone scintigraphy because of low uptake or a photopenic area in the tumor. In contrast, Tc-99m Sn-N-pyridoxy-
5-methyltryptophan
(Tc-99m PMT) whole-body scintigraphy reflects tumor viability, and the specificity of detection is so high that tumor structure can be shown well. Tc-99m PMT whole-body scintigraphy was helpful for evaluating the response to therapy and monitoring the course of the patient described here with bone metastasis from hepatocellular carcinoma.

Recent advances in the treatment of hepatocellular carcinoma (HCC) have prolonged patient survival. However, the number of patients with
bone metastases
identified during follow-up examinations has increased. Tc-99m Sn-N-pyridoxy-
5-methyltryptophan
(Tc-99m PMT) has been reported to accumulate at a high rate in HCC lesions and
bone metastases
. In the patient described here, whole-body scintigraphy showed accumulation of DTPA galactosyl human serum albumin (Tc-99m GSA) and Tc-99m PMT in
bone metastases
from HCC. The authors suggest that asialoglycoprotein receptors may be present in
bone metastases
from well-differentiated HCC. Tc-99m GSA whole-body imaging can be used to detect
bone metastases
from HCC and to evaluate hepatic reserve.

We report a 62-year-old man who presented with pain on the right side of his hip. CT revealed destructive masses in the right femur and left ilium. Histological examination indicated metastases from hepatocellular carcinoma, and further investigations revealed the primary tumor in the liver. Hepatobiliary scintigraphy using 99mTc N-pyrydoxyl-
5-methyltryptophan
and fused SPECT/CT clearly showed abnormal accumulation in these
bone metastases
from hepatocellular carcinoma.
