Malignant intraventricular meningioma with spinal metastasis through the cerebrospinal fluid.
A 67-year-old man developed a malignant meningioma of the right lateral ventricle at the trigone, for which he underwent total removal of the tumor and local irradiation. Six months after the operation, a spinal tumor developed and subtotal removal of the tumor was made. The spinal tumor was considered to be a metastasis via the cerebrospinal fluid in view of its histologic identity with the primary tumor, histologic findings of malignancy, absence of von Recklinghausen's disease, and lack of tumor attachment to the dura.
