Abstract
Glioneuronal tumor with ATRX alteration, kinase fusion, and anaplastic features (GTAKA) is a rare pathological subtype of the central nervous system, with currently limited research available. This case report details a 37-year-old woman who developed a new intracranial tumor 22 years after initial treatment (surgical resection and adjuvant radiotherapy) for a WHO grade 2 astrocytoma. The new lesion was histopathologically diagnosed as GTAKA, a distinct glioneuronal tumor entity, following which the patient received adjuvant radiotherapy with concomitant temozolomide chemotherapy. Although this pathological type is rare, the immunohistochemical and molecular findings, combined with the therapeutic approach in this case, contribute to a deeper understanding of the disease.
