OSTEOBLASTIC meningioma is extremely uncommon in childhood. This is understandable, as meningiomas in general are rare in children and the osteoblastic type is an infrequent variety. Keegan1 reported a meningioma in an 8 year old child. The 2 youngest patients in Cushing's series2 dated their symptoms from approximately three years of age, and there were only 6 preadolescents in his entire group. In his cases of osteoblastic meningioma the earliest symptoms began at 30 years of age.
The exact number of osteoblastic meningiomas reported in the literature cannot be tabulated because of the failure of authors to enumerate the number of cases of this tumor found in their reported series and because of the variation in classifications used. Cushing, in addition to reporting 6 cases of his own, described 5 recorded by other authors. Bailey3 reported 1 in his series of 27 meningiomas. Courville and Abbott4
