title: Calcifying pseudoneoplasm of the CNS.
abstract: Calcifying pseudoneoplasm or fibro-osseous lesion of the CNS is uncommon. We report a case in a 6-year-old boy who presented with generalized tonic-clonic seizures for 6 months. There was a calcified mass in the depth of the left temporal lobe, which on histology showed collagenous nodules surrounded by spindle cells and seperated by chondromyxoid matrix. The only other report of such a lesion in a child is of a 12-year-old boy with an epidural lesion at C-6 level. It is important to recognize this entity since it is slow growing with a good prognosis.
