Chordoma at the skull base, spine, and sacrum: A pictorial essay

Abstract

Chordomas are rare tumors believed to be arising from the notochord remnant in the axial skeleton. Diagnosis is often difficult since they show overlapping imaging features with other more common disease including metastases. Since individualized papers are only discussing the imaging features at different locations, the aim of this pictorial review is to have a comprehensive review on the common imaging findings of chordomas along the entire neuroaxis with a series of pathological proven cases in a local tertiary hospital in Hong Kong.

“…Further diagnostic workup requires advanced imaging; chordomas are typically midline, locally aggressive lesions [ 16 ]. Plain radiographs demonstrate lytic bony erosions, often associated with surrounding soft tissue swelling.…”
