Large meningioma of the foramen magnum in a 4-year-old child.

The case of a 4-year-old boy with 4 months' history of progressive quadriplegia is presented. The neuroradiological work-up, which included computed tomography scanning and magnetic resonance imaging, showed changes consistent with the diagnosis of a large mass lesion in the area of the foramen magnum. At operation a meningioma was completely excised. There was a gradual and almost complete neurological recovery.
