Abstract
- Meningioma of unusual age of onset, location, histogenesis and histologic type is reported. The patient, 4 year-old girl, had an intradural spinal meningioma arising from lumbar nerve root with no dural attachement. The meningioma revealed glycogen-rich, clear cell type with extensive and blocky hyalinization of the stroma. The tumor shared common fibrous sheath with attached lumbar nerve, and nerve fibers were scattered within the tumor. Ultrastructurally, the tumor cells had abundant glycogen particles, intermediate filaments and intercellular desmosomes. Hyalinized material revealed large amianthoid collagen fibers.
