Primary cranial chondrosarcoma in an uncommon cartilaginous tumours of which the myxoid variant is the least reported in the literature. This tumour accounts for 0.15% of all primary intracranial lesions and 6% of all skull base tumours. Chondrosarcomas are frequently misdiagnosed as chordomas, which have a different prognosis. Differential diagnosis is very important because, when treated with similar aggressive treatment strategies, chondrosarcoma has a much better prognosis than chordoma. We describe a 54-year-old female with a 9-month history of left ophtalmoplegia and increasing headache. MR imaging of the head showed a sellar and left parasellar mass. We performed a gross total removal of the mass via a left pterional approach. The histopathologic diagnosis was of a myxoid chondrosarcoma. A post-operative contrast-enhanced computed tomography (CT) scan of the head showed a total removal of the neoplasm. After surgery, the patient showed a transitory dysphasia with right hemiparesis, but they both considerably improved before discharge. Review of the literature was identified using the Medline database: only 10 cases in the worldwide literature were identified to report on this kind of tumour. We present a case report of myxoid chondrosarcoma, a rare variant of chondrosarcoma, with sellar and left parasellar localization. This histopathological type is a low-grade variant and its total removal is effective.
