Intradural spinal meningioma in a 20-month-old female.

Meningiomas in children account for less than 2% of all meningiomas, and their location in the spinal region is even less common. The authors present a case of a 20-month-old female who presented with lumbar back pain, neurogenic bladder and progressive paraparesis 6 months after she started to walk. Magnetic resonance imaging demonstrated an intradural extramedullary neoplasm extending from the tenth thoracic vertebra to the third lumbar vertebra. Complete excision of the tumor was performed by means of laminoplasty and the patient had a satisfactory postoperative recovery. Pathology and immunohistochemical studies diagnosed psammomatous meningioma.
