Chordomas are infiltrative tumors located within the intricate anatomy of the central skull base. It is well established that radical resections with no gross residual is associated with better prognosis….

Chordomas are rare, slow-growing, infiltrative tumors that are most often identified in the fourth to sixth decades of life. 1 They account for 1 to 4% of all primary bone…

Chordomas represent less than 1% of intracranial tumors and 3% of primary bone tumors, with an incidence of 0.08 per 100,000, peaking in the sixth decade, with a 2:1 male…

Chordomas are rare neoplasms arising from remnants of the notochord, an embryonic precursor to the axial skeleton, and can occur anywhere along the spinal axis. 1 They are relatively uncommon…

The craniovertebral junction is the region of the neural axis spanning from the foramen magnum of the skull base to the first and second cervical vertebrae (the atlas and axis,…

The frontobasal approach is designed to expose strictly extradural lesions of the anterior fossa as well as middle clivus and inferior clivus, with little or no lateral extension. For such…

The notochord is a mesoderm-derived, rod-shaped organ found in embryos of all chordates that defines the craniocaudal axis of the embryo. Chordates comprise cephalochordates, urochordates, and vertebrates. They probably originated…

Chordomas are rare tumors that arise from remnants of the notochord. They are encountered in the skull base and upper cervical spine or in the sacrum. Skull base chordomas are…
