Chordomas are rare tumors that can develop anywhere along the craniospinal axis. These tumors present challenges with respect to diagnosis and treatment due to a high rate of recurrence, even after multiple surgeries, and the propensity to involve any region within the craniospinal axis. New developments in radiation therapy have improved recurrence-free survival in patients with chordomas. Different regimens of chemotherapy and molecularly-targeted therapies, as adjuvants to surgery, have been described in individual case reports and case series. The purpose of this paper is to describe a case of clival chordoma and review recent developments in diagnostic and therapeutic options. A 77-year-old female was referred because of diplopia and progressively worsening headaches. Head imaging revealed a large expansile and erosive mass in the skull base. The patient underwent a successful endoscopic endonasal trans-sphenoidal resection of the mass, with biopsy confirming the diagnosis of chordoma. Postoperatively, the patient experienced an improvement in neurological symptoms. Chordomas can present a diagnostic challenge due to the rare occurrence and a tendency to involve any region within the craniospinal axis. [ABSTRACT FROM AUTHOR]
