Abstract
Only 1-2% of all meningiomas are intraventricular in location. Metastasis from a histologically "benign" meningioma is a rare, but well-documented event. However, there are only four reported cases in the literature of metastatic spread from a purely intraventricular meningioma. The tumors in these reports had a frankly malignant histology or were associated with surgical manipulation and recurrence of the primary lesion. In this report, the authors present a rare case of the concurrent presentation of a histologically benign intraventricular meningioma and a solitary lung lesion which proved to be metastatic meningioma.
