M\u00c9TODO: Foram estudados de forma retrospectiva 10 pacientes com ET e diagn\u00f3stico histol\u00f3gico comprovado de ASCG. Quatro pacientes eram do sexo masculino e seis do feminino, com idade m\u00e9dia de 15,7 anos. Todos os pacientes foram investigados com RM, sendo os exames revisados por dois radiologistas, havendo decis\u00e3o por consenso sobre os achados de imagem. Foram analisados os seguintes achados: localiza\u00e7\u00e3o, dimens\u00f5es, intensidade de sinal em T1\/T2, realce p\u00f3s-contraste e outros achados associados. RESULTADOS: Todos os pacientes apresentaram les\u00e3o \u00fanica sugestiva de ASCG, medindo entre 1,5 cm e 8 cm em seu maior di\u00e2metro. Oito les\u00f5es foram encontradas junto ao forame de Monro (80%) e duas adjacentes ao corpo do ventr\u00edculo lateral (20%). Os tumores apresentavam nas imagens pesadas em T1 m\u00e9dio sinal (70%) e em T2 alto sinal (100%), com realce intenso ap\u00f3s a administra\u00e7\u00e3o do gadol\u00ednio (100%). CONCLUS\u00c3O: Os astrocitomas subependim\u00e1rios de c\u00e9lulas gigantes em pacientes com ET em geral apresentam-se como les\u00e3o \u00fanica pr\u00f3xima ao forame de Monro, com m\u00e9dio sinal nas imagens ponderadas em T1, alto sinal em T2 e realce intenso ap\u00f3s a administra\u00e7\u00e3o de contraste.<\/jats:p>","DOI":"10.1590\/s0004-282x2007000200023","type":"journal-article","created":{"date-parts":[[2007,9,28]],"date-time":"2007-09-28T03:00:36Z","timestamp":1190948436000},"page":"313-316","source":"Crossref","is-referenced-by-count":6,"title":["Astrocitoma subependim\u00e1rio de c\u00e9lulas gigantes em pacientes com esclerose tuberosa: achados em resson\u00e2ncia magn\u00e9tica de dez casos"],"prefix":"10.1590","volume":"65","author":[{"given":"Karina","family":"Takata","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emerson L.","family":"Gasparetto","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia da Costa","family":"Leite","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leandro T.","family":"Lucato","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Umbertina C.","family":"Reed","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hamilton","family":"Matushita","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo Henrique P. de","family":"Aguiar","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S\u00e9rgio","family":"Rosemberg","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"448","DOI":"10.1067\/mjd.2001.111627","article-title":"Tuberous sclerosis: Part I.
