Resumen

Syringomyelia is the presence of a fluid-filled cavity in a spinal cord segment. The typical presentation includes impaired pain and temperature sensation and crude touch, preserved proprioception, and progressive weakness. We present the case of a 31-year-old male patient with weakness and hypotrophy in his hands without sensory symptoms. Electromyography showed neurogenic involvement of the bilateral C8/T1 myotomes, initially interpreted as Hirayama disease, but neuroimaging revealed extensive cervicothoracic syringomyelia. The patient underwent surgical management and recovered well. This is an atypical form of syringomyelia that mimics conditions such as juvenile monomelic amyotrophy. Copyright
