title: Primary diffuse leptomeningeal oligodendrogliomatosis: A case report and literature review.
abstract: Primary leptomeningeal oligodendrogliomatosis (PLO) is a rare low-grade intracranial and spinal canal subarachnoid neoplasm without an obvious primary neoplasm in the brain or spinal cord parenchyma. We present here the serial progression of radiological findings of this rare disease in a 2-year-old male child whose clinical status deteriorated over a period of 4 months with the main complaint of partial seizures. During this period, the MR findings progressed from mild hydrocephalus with minimal leptomeningeal enhancement to leptomeningeal multiple cystic lesions in the entire neuraxis including the spine.
