"Os gliomas múltiplos são relativamente raros e podem ser classificados didaticamente de acordo com: a) a época da apresentação, em precoces (quando presentes desde o diagnóstico inicial) ou tardios (quando presentes durante a evolução); e b) as características dos exames de imagem, em multifocais (quando há evidência de contiguidade das lesões) ou multicêntricos (quando não é possível identificar contiguidade das lesões). Entre os 212 pacientes com diagnóstico anatomopatológico de glioma, acompanhados prospectivamente no setor de neuro-oncologia de março/90 a setembro/99, 15 (7%) apresentaram lesões múltiplas. Descrevemos 4 casos característicos de cada uma das possíveis apresentações: multicêntrico precoce, multicêntrico tardio, multifocal precoce e multifocal tardio, com ênfase nas características de imagem e possíveis diagnósticos diferenciais. O diagnóstico diferencial das lesões múltiplas no sistema nervoso central inclui doenças inflamatórias e infecciosas, além de metástases. A possibilidade de tratar-se de tumores de origem glial, entretanto, deve ser sempre lembrada, mesmo naqueles pacientes com diagnóstico de neoplasia sistêmica conhecida, conforme já descrito na literatura. O diagnóstico histológico se impõe, uma vez que as características de imagem não permitem diagnóstico de certeza."
