Anaplastic oligodendroglioma with drop metastasis to the spinal cord.

Although cerebrospinal fluid spread by malignant brain tumors is well recognised, cases of drop metastasis to spinal cord by intracranial oligodendroglial tumors have only been rarely described. We described a 61-year-old man who developed diffuse spinal metastases and cord compression 20 months after resection of a frontal lobe anaplastic oligodendrogliomas. To our knowledge, this represents the eighth recorded case in the literature.
