BONE MARROW METASTASIS IN ANAPLASTIC OLIGODENDROGLIOMA

Abstract

Oligodendroglioma is a rare primary brain tumour. These tumours rarely metastasis extraneurally because of the absence of a lymphatic system, the presence of the blood-brain barrier and the patient's poor overall survival. Oligodendroglioma may spread via the cerebrospinal fluid or after surgical intervention. Metastasis to bone marrow is extremely rare. Oligodendroglioma is now considered a chemosensitive disease. If chemotherapy leads to prolonged survival, we may see more extraneural metastases in future.
