title: Intracranial chondrosarcoma: a case report and review of the literature.
abstract: OBJECTIVE
  Chondrosarcomas rarely occur intracranially away from the skull base. We present a case of a supratentorial dural-based, low-grade classic chondrosarcoma and emphasize salient imaging findings that assist in its diagnosis.
  
  
  METHODS
  A 23-year-old female presented with new onset seizures. Multiple radiographic imaging studies identified a large left frontal mass with radiological findings that suggested the correct diagnosis.
  
  
  METHODS
  The patient underwent a left frontal craniotomy and gross total resection of the lesion and associated dura.
  
  
  CONCLUSIONS
  Intracranial chondrosarcomas away from the skull based are extremely rare malignancies. As with other extra-axial masses, they often grow to a relatively large size before generating symptoms. Careful analysis of CT, MR, and angiographic imaging characteristics should suggest the correct diagnosis.
