title: Primary intradural mesenchymal chondrosarcoma of the spine in a child.
abstract: We report a primary intradural mesenchymal chondrosarcoma of the spine in a 3-year-old girl. MRI revealed a markedly enhancing oval mass associated with focal areas of low signal intensity extending from T11 to L1. The lesion was located posterolateral to the right side of the spinal cord, pushing the conus medullaris and cauda equina anteriorly and to the left. The adjacent spinal cord also showed serpiginous areas of flow void. The mass was completely removed. Microscopic examination and immunohistochemical studies confirmed the diagnosis of mesenchymal chondrosarcoma. The patient was free of symptoms after surgery.
