Question

which of the following spinal cord lesions has a primary etiology of trauma?
transverse cord lesion
hemicord lesion
anterior cord syndrome
two of the above

Explanation:

• Transverse cord lesions often result from severe trauma (e.g., spinal fractures) that damages the entire cross-section of the spinal cord.
• Hemicord lesions (Brown-Séquard syndrome) are frequently caused by traumatic injuries that affect one half of the spinal cord, such as stab wounds or spinal fractures.
• Anterior cord syndrome most commonly arises from ischemia (reduced blood flow) to the anterior spinal artery, not primary trauma.

Thus, two of the listed lesions have trauma as a primary etiology.

Answer:

Two of the above
