Abstract
Secondary leptomeningeal gliomatosis is a condition known as a result of invasion of the subarachnoid space or the ventricular system of primary intraparenchymal glioma. In this article, we present a 7-year-old boy presented with neck and back deformity and deterioration of gait. Cranial and spinal magnetic resonance imaging revealed lesions in the supratentorial and infratentorial areas, in the brainstem downward the spinal cord. Disseminated oligodendrogliomatosis is extremely rare and our case we present is the 24(th) in the literature.
