Endoscopic Endonasal Clival Chordoma Resection with Significant Progression-Free and Overall Survival
Clival chordomas are a rare type of intracranial neoplasms that arise from the remnant of the primitive notochord and present with local invasion and bony destruction. We present a rare case of a patient with clival chordoma, with left abducens nerve paresis as clinical manifestation, diagnosed via magnetic resonance imaging and computed tomography. The patient was treated utilizing the extended endoscopic endonasal approach and postoperative conventional radiotherapy, following significant progression-free and overall survival of 8 years and 3 months, with no recurrent disease, confirmed via multiple controls contrast-enhanced MRI scans. In regard to this case and the available literature, a conclusion can be made that the effectiveness of endoscopic endonasal approach proves superior to other surgical approaches, while considering lesion characteristics, clinical parameters and postoperative goals and expectations.
