Childhood meningiomas. Experience in the modern imaging era.
Twenty children with meningiomas (ages 18 months to 17 years) received initial therapy at the Children's Hospital of Philadelphia between January 1975 and June 1991, accounting for 2% of children with primary brain tumors seen during that time interval. All were verified histopathologically, and none had had prior irradiation. Fifteen were male and 5 female. Fifteen tumors were intracranial, all located supratentorially. Two of these also had a component within the optic canal. One tumor was entirely within the orbit. Four meningiomas arose within the spinal canal. Associated conditions were neurofibromatosis (NF) type I (1 patient), NF type II (2 patients), and a facial alveolar rhabdomyosarcoma (1 patient). A gross total resection as documented by postoperative scan and operative note was accomplished in 12 patients. Four of these relapsed, at a mean of 3.5 years from initial surgery. In 4 patients a near-total resection (> 90%) was performed. Of these, 2 progressed at 9 months and 1.5 years. One of these died of complications associated with reoperation. In 4 patients a partial resection (50-90%) was performed. Two of these progressed at 4 months and 1 year, and the other 2 have been followed for less than 2 years. Five patients received radiation therapy (RT). One patient received RT as adjunctive therapy after primary surgery because of papillary histology. The other 4 had RT following reoperation for recurrence at a mean of 1.5 years from diagnosis (range, 7 months to 2 years). These 4 patients remain alive and with stable disease at a mean of 6 years from diagnosis (range 2-8.8 years).(ABSTRACT TRUNCATED AT 250 WORDS)
