Clival Cordoma

A 61-year-old female patient was admitted to the hospital with a headache that lasted for 2 months and diplopia for 5 days. In the magnetic resonance imaging examination, there is a soft tissue mass originating from the sellar region, extending to the suprasellar area, compressing the optic chiasm, destroying the clivus on the right, and extending into the sphenoid sinus. The lesion was diagnosed as chordoma. This patient’s chordoma is a rare malignant tumor originating from notochord remnants. It is located in the skull base and spinal bones. It is a rare tumor clas- sified under bone and soft tissue sarcoma.
