Pediatric spinal clear cell meningioma. Case report.

In this report the authors describe a unique case of spinal clear cell meningioma in a 13-year-old girl. Clear cell meningiomas (CCMs) are not uncommon. To the authors' knowledge, 14 cases of pediatric CCM occurring in the spinal canal have been reported. Factors lending resistance to meningioma initiation and invasion are analyzed. This 13-year-old girl presented with pain radiating down her left leg. Admission MR imaging showed an inhomogeneous enhancing intradural-extramedullary mass at the L4-5 level. Resection revealed a CCM, and radiotherapy was subsequently administered. Postoperatively there has been no recurrence in > 2 years. In this paper the authors report a case of CCM and provide a comprehensive literature review on this disease. Current recommendations for its management are still debatable, especially in the pediatric population, and the authors propose an algorithm for its treatment and surveillance.
