Hepatocellular carcinoma metastasizing to the skull base involving multiple cranial nerves

Figure 3 Brain MRI image. A: Unenhanced coronal T1-weighted image reveals ill-defined mass around the sella turnica. The mass shows intermediate signal intensity; B: A mass reveals high signal intensity on coronal T2-weighted image; C: Unenhanced saggital T1-weighted image reveals ill defined mass involving the sella turcica. D, E: On contrast-enhanced saggital (D) and transverse (E) T1-weighted images, the mass shows inhomogeneous intermediate enhancement and involves the clivus, cavernous sinus and petrous apex. Meningeal thickening between the posterior sella turcica and the clivus and dilation of the superior carotid vein are observed.
