Mesenchymal chondrosarcoma is a rare aggressive neoplasm typically affecting the bones of young adults.It may also arise in somatic soft tissue,the CNS and other organs.We report a case of mesenchymal chondrosarcoma arising from the cerebral falx in a 39-year-old woman with symptoms relating to mass occupying effect.Histological examination demonstrated a characteristic biphasic histological pattern composed of highly undifferentiated small round cells and islands of well-differentiated hyaline cartilage.We discuss the features of mesenchymal chondrosarcoma arising in the CNS,the important differential diagnoses of tumors with histological likeness within the CNS,the genetic features,and the treatment.The short running title: Giant intracranial mesenchymal chondrosarcoma.
