Question

what is the most likely diagnosis for a patient reporting an inability to feel hot shower water on their shoulders? anterior spinal artery syndrome cervical spine myelopathy syringomyelia peripheral neuropathy

Explanation:

Syringomyelia is characterized by a fluid-filled cyst (syrinx) in the spinal cord, which often causes a loss of pain and temperature sensation in a cape-like distribution (including the shoulders) while preserving other sensations. Anterior Spinal Artery Syndrome affects motor and touch sensation but not typically isolated temperature loss in this pattern. Cervical Spine Myelopathy causes broader spinal cord dysfunction like weakness and gait issues. Peripheral Neuropathy usually affects distal limbs (hands/feet) symmetrically, not isolated shoulder temperature sensation.

Answer:

Syringomyelia
