Key Points

  • To describe a rare instance of solitary zygomatic bone metastasis stemming from hepatocellular carcinoma and its imaging characteristics.
  • Used FDG PET/CT to detect metastasis in the zygomatic bone.
  • Patient previously treated with transarterial chemoembolization.
  • Conducted a pathologic examination to confirm diagnosis.
  • FDG PET/CT revealed increased uptake in the zygomatic bone with SUVmax of 3.9.
  • Metastasis diagnosis was confirmed through pathologic examination.

Abstract

Hepatocellular carcinoma involving the solitary zygomatic bone is quite rare. Here we present FDG PET/CT findings of the right zygomatic bone metastasis from hepatocellular carcinoma in a patient after transarterial chemoembolization 2 years ago. 18 F-FDG PET/CT showed increased 18 F-FDG uptake in the right zygomatic bone with SUVmax of 3.9. Finally, the diagnosis of solitary zygomatic bone metastasis was confirmed by pathologic examination.
