Zitat: Meningiomas in children and adolescents.

PURPOSE: To review the diagnosis, treatment, and long-term outcome of children and adolescents with meningiomas diagnosed by a single institution and compare these findings with other published data.

PATIENTS AND METHODS: A 25-year retrospective analysis of 18 patients with meningioma diagnosed at Children's Hospital Medical Center, Cincinnati, Ohio was performed. A literature review of published reports was undertaken to compare evaluation. treatment, and outcome for similar patients.

RESULTS: Patients ranged from ages 19 months to 17 years at diagnosis. The most common symptoms were headache (5) and seizures (5), although most patients had multiple symptoms. The brain was the primary location of tumor in 17 patients, with the remaining tumor located in the spine. Comorbid diagnoses were common, including developmental delay, balanced chromosomal translocation, type I diabetes mellitus, neurofibromatosis, Klinefelter syndrome, and seizures. Eleven patients had gross total resection performed. Four patients had malignant meningiomas. Two patients were treated with radiotherapy only, one had chemotherapy only, and two underwent both. Karyotype abnormalities most commonly involved chromosome 22, but other abnormalities were present. Sixteen patients remain alive and two patients, having had malignant tumors, are dead of disease. Long-term sequelae include seizures, diabetes insipidus, blindness, neuropsychologic abnormalities, and multiple surgical procedures. Only three patients are self-described as being without problems.

CONCLUSIONS: Based on this study and a literature review, the roles of surgery, radiation, and chemotherapy remain unclear. Long-term outcome for patients with meningiomas, especially as it relates to cognitive function, is rarely reported. This group of patients has a high incidence of morbidity associated not only with treatment but also with preexisting diseases. These data indicate the need for a national cooperative group study to better understand the evaluation, treatment, and outcome for children and adolescents who are treated for meningiomas.

Long-term follow up of children with meningiomas in Denmark: 1935 to 1984.

OBJECT: Meningiomas in children are rare, infrequently described in the literature, and often associated with neurofibromatosis Type 2 (NF2). The authors report a series of 22 children treated for an intracranial meningioma in Denmark between 1935 and 1984.

METHODS: Of 1542 cases of pediatric intracranial tumors in children younger than 15 years of age, 22 harbored meningiomas. Three children suffered from NF. The male/female ratio was 8:14. The mean age at the time of diagnosis was 5 years for boys and 11.5 years for girls. At the time of diagnosis all tumors were large. All patients underwent surgery. In 20 cases, the final histological diagnoses were low-grade and in two cases high-grade tumors. The follow-up period ranged from I to 45 years (mean 16 years). Two patients were lost to follow up. Four of seven boys and three of 13 girls survived. Five of 13 children in whom the tumor was completely removed survived, whereas two of seven in whom the lesion was partially removed survived. The mean survival time in children who died during follow up was 10 years. Two children with anaplastic meningioma remain alive.

CONCLUSIONS: The long-term prognosis for surgically treated children with intracranial meningiomas was worse than expected. Some reasons for this may have been the late diagnosis and related large size of the tumor during a period of limited diagnostic capacity prior to the computerized tomography and magnetic resonance imaging eras, and the association of NF2 with multiple tumors of the central nervous system. Complete resection is not always possible and should be performed as an image-guided operation
