Los meningiomas son tumores raros en los niños, siendo especialmente inusual su localización raquídea y excepcional su origen en la duramadre de la teca lumbar. Presentamos el caso de una niña de 12 años con un meningioma de cauda equina. En concordancia con la literatura el síntoma inicial fue lumbalgia con irradiación radicular, siendo escasos los hallazgos de la exploración neurológica, que se limitaban a la presencia de signos piramidales en ambas extremidades inferiores. Fue intervenida mediante una laminoplastia en puerta abierta, consiguiéndose la resección completa de la tumoración sin déficit neurológico postoperatorio. La niña permanece asintomática dos años después de la cirugía.
Meningiomas are unusual in childhood, and the intraspinal location is wery uncommon. Those arising from lumbar dura matter are the most rare among spinal neoplasms of meningeal origen. We present the case of a 12-years-old girl with a cauda equina meningioma. As impreviously reported cases, the initial complain was back pain with radicular irradiation. The girl had few neurological findings, with pyramidal signs of both lower limbs as single neurological impairment. She underwent surgical treatment through an open door laminoplasty and the tumour was completely removed without neurological deficit. After 2-year of follow-up she remains asymptomatic.
