The clinical analysis of pediatric meningioma: 5 cases

Five cases of pediatric meningioma were reported with special emphasis on the clinical features. These cases consisted of three boys and two girls be tween eight and fifteen years old. Two were fair meningioma, two were suprasellar, and one was petroclival. One fair meningioma was associated with Neurofibromatosis II, and a suprasellar case had no dural attachment, but had cystic component after recurrence. Histologically, there were three meningothelial, one transitional, and one fibrous meningioma. No malignant meningioma was found among any of the cases. Two cases received postoperative irradiation and had no recurrence. A fair meningioma with Neurofibromatosis II and a suprasellar with no dural attachment had evidence of recurrence. The latter suffered from severe neurological deficits after reoperation. It was suggested that irradiation against residual tumor should be considered. However, total removal should be carried out in pediatric cases of meningioma. The authors concluded that our cases had features intermediate between adult meningiomas and pediatric meningiomas because the majority of cases were senior children.
