The patient went on to have a resection demonstrating a meningioma with a superimposed hepatocellular metastasis.

Subsequent CT of the liver demonstrates an arterially enhancing mass in the posterior aspect of the left lobe, with washout on portal venous phase.
Case Discussion
Metastases to meningiomas are a rare but recognized event.
