Question

what condition causes loss of pain and temperature at the shoulders and upper arms?
○ cervical myelopathy
○ syringomyelia
○ multiple sclerosis
○ peripheral neuropathy

Explanation:

Syringomyelia is characterized by a fluid-filled cyst (syrinx) in the spinal cord, which typically damages the spinothalamic tracts that carry pain and temperature sensation. A classic presentation is a loss of pain and temperature sensation in a "cape-like" distribution covering the shoulders and upper arms. Other conditions: Cervical myelopathy primarily causes motor weakness and broad sensory issues; multiple sclerosis has varied neurological symptoms not specific to this distribution; peripheral neuropathy affects distal limbs first.

Answer:

Syringomyelia
