Meningiomas em pacientes pediátricos: relato de 2 casos

Abstract: RESUMO -Os meningiomas correspondem de 1% a 4% das neoplasias intracranianas primárias em pacientes pediátricos; a incidência nesta população aumenta de acordo com a faixa etária. Não há predominância quanto ao sexo, ao contrário do que acontece na população adulta onde predominam no sexo feminino. Relatamos dois casos de meningioma em crianças, discutindo os aspectos clínicos, radiológicos e histológicos desta entidade. O primeiro paciente é do sexo masculino, com 2 anos de idade e apresentava com crises conv… Show more

“…14,95 A high frequency of intra-or peritumoral cysts (15%) results from this analysis, whereas in the adult population, cystic forms are present in 2% to 4% of all meningiomas. 2,17,32,91,92,102,108,109 Cystic prevalence in the first 2 years of life can be ascribed to the tendency of cystic tumors to manifest earlier than solid ones. Effectively, we have found the average duration of the clinical history of meningiomas in pediatric patients (1.2 years) to be shorter than meningiomas at other ages (2.8-3.5 years).…”

“…12,13,17,54,59,60,78 The lack of dural attachment is probably due to derivation of the tumor from leptomeningeal elements lodging within the parenchyma or in or near the ventricles rather than from the dura mater. 91 Histologically, the meningiomas were mainly meningothelial (32%), 19,20,91,94,97,99,102,104,[106][107][108][109][110] followed by fibrous (25%), 9,19,20,91,[99][100][101]104 transitional (22%), 19,20,97,99,103,104,[106][107][108][109] anaplastic (9%), 19,20 angiomatous (6%), 19,20,104,107 psammomatous (2%), 99,104 atypical (1.2%), 99,100,…”
