A 55-year-old man discovered that he had pain in the neck and right arm and weakness in extending his fingers of his right hand with loss of sensation in the right thumb and middle fingers. A neurological examination further revealed a weakness of the right biceps reflex, but other neurological signs could not be detected. The most likely diagnosis of this individual is ?
1. Syringomyelia involving the cervical cord
2. A knife wound of the right arm completely severing nerves innervating the biceps muscle
3. Prolapse of a cervical disk
4. Poliomyelitis involving the cervical cord
5. AIDS
