Question

which location is the least likely for a chordoma? a) c2 vertebral body b) spheno - occiput c) clavicle d) sacrococcygeal

Explanation:

Chordomas are rare bone tumors that develop from embryonic notochord remnants. The notochord's remnants are typically found along the axial skeleton: the sacrococcygeal region (most common), the spheno-occipital area of the skull base, and vertebral bodies (like C2). The clavicle is part of the appendicular skeleton, with no notochord remnants, making it the least likely site for a chordoma.

Answer:

C) clavicle
