Papillary glioneuronal tumor--a new tumor entity.
Glioneuronal neoplasms of the CNS comprises a heterogeneous group of generally low-grade tumors expressing glial and neuronal cells of varying differentiation. Recently, a new variant of the glioneuronal tumors has been identified. We present a case of a glioneuronal tumor located in the left frontal lobe of a 16-year-old boy who developed seizures 6 months after brain concussion. MR scan demonstrated an irregular, but well circumscribed, mixed cystic and solid tumor with contrast enhancement in the solid part. Histology showed a papillary glioneuronal tumor. The tumor is indolent with no sign of recurrence after gross total resection.
