title: Intra-parenchymal mesenchymal chondrosarcoma of the cerebellum: case report and review of the literature.
abstract: A 44-year-old male presented with a 3-week history of clumsiness and numbness of the left hemibody. CT scan and MRI revealed a 2 cm mass in the right hemisphere of the cerebellum. The patient underwent a sub-occipital craniotomy with gross total resection of the intra-parenchymal lesion. On pathology, the lesion was found to be compatible with a mesenchymal chondrosarcoma. The patient received adjuvant radiation treatment and remains free of disease 60 months after completion of treatment. Mesenchymal chondrosarcomas are neoplasms that rarely arise intra-cranially. Thirty cases have been found in the literature. Our case resembles more closely six of these cases because the tumour had no dural attachment. We describe our case in more detail and review similar cases found in the English literature.
