抄録

A 63-year-old man, previously well, presented with the rapid development of compression myelopathy due to metastatic tumor in the 8-10th thoracic vertebrae. He died of serious infection of the lungs on 48th day after admission. At autopsy, hepatocellular carcinoma (Edmondson's grade III) with liver cirrhosis was found. The metastasis occurred in the 8-10th thoracic vertebrae, and the hemiazygos vein and the external vertebral venous plexus were packed with the tumor cells. However, there was no other conspicuous metastasis, except in capillaries of the adrenals, veins in the spleen and small branches of the pulmonary artery. The present case demonstrated that metastasis of hepatocellular carcinoma in the vertebrae can occur through the azygos and vertebral venous system, namely the portal vein, esophageal veins, the hemiazygos vein and the external vertebral venous plexus, as predicted by Batson.
