A case of multiple clear cell meningioma of cauda equina in a 10-year-old girl is reported. She was referred with 3-month history of painful episodes of backache and a markedly sore right leg and admitted for further examination. No neurological deficiency was recognized in physical examination. Magnetic resonance imaging scan clearly exhibited heterogenous tumors at the level of Th12 and L2 following roentgenogram that did not show any abnormal findings. Tumor resection was performed by thoraco-lumbar en block laminectomy with TSaw. Subsequently, resected laminas were replaced to obviate possible spinal kyphosis. The patient's recovery was uneventful. Clear cell meningioma was discerned by pathological examination, whose findings including granules consistent with glycogen and ultrastructure of meningioma.Younger patients who undergo multiple laminectomy have been reported to incur kyphotic change at involving the spine. In order to obviate such deformities, we think that the posterior element of the spine should be reconstructed.
