Cystic Chordoma of the Cavernous Sinus

Özet

Chordomas are the tumors commonly involving base of skull which are predominantly solid in consistency. A cystic chordomaof the cavernous sinus is an extremely rare entity and has never been reported. We report a 26-year-old male presenting withgradually progressive right-sided sixth nerve palsy and headache. Computed tomography and magnetic resonance imaging ofthe brain showed a cystic lesion in the right cavernous sinus. The patient was successfully treated using a transnasal endoscopictranssphenoidal approach. Histopathological examination of the lesion revealed chordoma. Our case is the first report of such acondition. Chordoma should be considered in the differential diagnosis of cystic lesions in the parasellar location. We briefly reviewthe radiology, the pathology and management dilemmas of such lesions.
