We describe a 25\u2010year\u2010old patient who sustained complete traumatic spinal cord injury at the thoracic level and presented with rhythmic neck muscle spasms and upper limb muscle myoclonic jerks 1 month after trauma. Magnetic resonance imaging revealed syrinx formation between C3 and T1. Lumbar\u2010peritoneal shunt and decompression were performed. The symptoms completely disappeared after surgery. This report highlights that rhythmic neck muscle spasms and upper limb muscle myoclonic jerks can be the initial and only manifestations of syringomyelia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
