Abstract

Intracranial teratoma corresponds to a type of germ cell tumor (GCT) of the central nervous system which is characterized by the presence of tissues derived from the germinal layers, which may have hair and adipose tissue inside, for example. The literature on the subject is scarce, and the T2 magnetic resonance imaging (MRI) pattern commonly found is that of a heterogeneously hyperintense mass and, after contrast, teratoma presents heterogeneous enhancement. Therefore, the present case report aims to present atypical results of a GCT in a young adult woman. Data analysis and compilation were performed from medical records, as well as the neuroimaging study. Thus, the present case report demonstrates neuroimaging findings with homogeneous postcontrast enhancement in an adult patient, with an unusual age profile when compared with most of the studies published so far. This demonstrates that it is possible to have atypical neuroimaging findings for mature teratomas and that they can behave in a less aggressive way, not requiring adjuvant postoperative therapies.

Resumo

Teratoma intracraniano corresponde a um tipo de tumor de células germinativas (TCG) do sistema nervoso central que se caracteriza pela presença de tecidos derivados das camadas germinativas que podem conter pelos e tecido adiposo no seu interior, por exemplo. A literatura sobre o assunto é escassa e o padrão de ressonância magnética (RM) T2 comumente encontrado é o de massa heterogeneamente hiperintensa e, após contraste, o teratoma apresenta realce heterogêneo. Pensando nisso, o presente relato de caso tem como objetivo apresentar resultados atípicos de TCG em uma paciente mulher adulta jovem. Para isso, foi realizada a análise e a compilação dos dados em prontuário, assim como um estudo de neuroimagem. Assim, o presente relato de caso demonstra achados de neuroimagem com realce homogêneo pós-contraste em indivíduo adulto com perfil etário incomum ao descrito na maioria dos estudos até o momento. Isto demonstra que é possível a confirmação dos achados de neuroimagem atípicos para os teratomas maduros e que eles podem se comportar de forma menos agressiva, dispensando terapias adjuvantes no pós-operatório.
