Bone recurrence. Axial contrast-enhanced CT images on the arterial phase (a–e) show bone recurrence of HCC (arrows) in different patients. Bone metastases from HCC are typically lytic (bone destruction), expansive, and characterized by soft tissue mass with typical hyperenhancement on the arterial phase. The sites of recurrence are vertebrae (a), ribs (b), right iliac bone (c), and skull (d, e). In patients with recurrent HCC in the right side of the anterior and middle cranial fossae (d), the lesion causes bone destruction with invasion of the orbit and ethmoid
