N2 - Background: Metastatic renal cell carcinoma to the choroid plexus is a rare condition and can be easily confused with meningioma. Methods: A 61-year-old female presented with progressive neurologic deterioration and MRI findings of obstructive hydrocephalus and a homogeneously contrast enhancing 3 cm oval mass in the trigone of the left lateral ventricle. Results: Despite radiologic, intraoperative gross features, and frozen pathology all consistent with meningioma, the final pathology revealed metastatic renal cell carcinoma. Conclusion: Renal cell carcinoma metastatic to the choroid plexus can mimic intraventricular meningioma. We present a review of the literature and comparison of the radiological features of meningiomas and metastatic renal cell carcinoma. We also discuss the use of an under-utilized technique, the contralateral transcallosal approach, in the surgical treatment of this intraventricular lesion.
