[Extraneural metastasizing oligodendroglioma (author's transl)].

A 40-year-old man suffered from a right parietal oligodendroglioma. Two months after the onset of clinical symptoms complete removal of the tumor was attempted. At second craniotomy four years later the tumor was found to invade the falx cerebri. The patient died seven years after the first admission to the hospital. Necropsy revealed the right parietal oligodendroglioma invading the sagittal sinus and the left hemisphere as well as metastases in the lung, the lymph-nodes, the vertebra, and the femur.
