ABSTRACT
Non-skull-base intracranial chondrosarcomas are extremely rare. We present a patient with a classic falcine chondrosarcoma and review the radiological features that may aid in a pre-operative diagnosis, as well as the adjuvant treatment options. A 32-year-old woman presented with a 5-year history of progressive weakness in her right leg. MRI scan demonstrated a 4.9 x 4.3 x 2.7 cm irregular parasaggital mass in the left frontoparietal region that was in contact with the falx. A left fronto-parietal craniotomy was performed and gross total excision was achieved. Intracranial chondrosarcomas that occur above the skull base tend to be of the mesenchymal variety. Classic chondrosarcomas of the falx are rare. The management of these tumours is surgery, with adjuvant radiotherapy for incompletely excised lesions.
