Popis: The embryonal tumor with abundant neuropil and true rosettes is a rare and highly malignant variant of embryonal brain tumors. It usually affects infants and young children under the age of 4 years and exhibits a very aggressive course with a dismal prognosis. For the 68 cases reported to date the mean age at diagnosis was 25.42 months (range 3-57 months). Survival data are available for 48 children (including our case): the median overall survival is 13.0 months, though 6 (9%) of the children have had a relative long survival (>30 months). The aggressive combined treatment, involving primary surgical tumor removal, adjuvant polychemotherapy, including high-dose chemotherapy with stem cell transplantation, radiotherapy and radiochemotherapy, might play an important role in the longer survival. We have performed a literature review and we present here a multimodal-treated case of a 2- year-old girl with a long survival, who was reoperated when recurrence occurred. The residual tumor demonstrated a good response to temozolomide radiochemotherapy (craniospinal axis + boost) and followed by maintenance temozolomide. The described complex aggressive treatment option might be considered for future cases of this tumor entity.
