RELATO Homem, 29 anos, com episódios de crises convulsivas e diagnóstico de hemorragia intraparenquimatosa. Durante a cirurgia, foi identificada lesão bem delimitada. A histologia demonstrou neoplasia fusocelular com atipias e numerosas mitoses. Os únicos marcadores imuno-histoquímicos positivos foram vimentina e S-100. O diagnóstico foi de sarcoma indiferenciado de alto grau.CONCLUSÃO:

They are aggressive with poor prognosis, and mostly treated with radical resection. REPORT 29 year-old male patient with episodes of seizures and diagnosed with intraparenchymal hemorrhage. During the surgery a well-defined lesion was identified. Histology showed a spindle cell neoplasm with atypia and numerous mitoses. The immunohistochemical markers were positive only for vimentin and S-100. The diagnosis was high-grade undifferentiated sarcoma.CONCLUSION:
