CLEAR-CELL MENINGIOMA OF THE CAUDA-EQUINA

Meningiomas are rare rumours in children and lumbar lesions are except ional. We report a clear-cell meningioma (CCM) of the cauda equina in a 10-year-old girl. The tumour was diagnosed by MRI, showing an enhanc ing intradural mass extending from L1 to L4. Pathology and immunohisto chemical study demonstrated a CCM. The patient had a recurrence 6 mont hs after the operation requiring further surgery. CCM are rare lesions , characterised by abundant cytoplasmic glycogen particles. Complete s urgical removal is necessary because, despite their benign histologica l appearance, CCM are potentially aggressive and may recur,spread loca lly and even metastasize.
