Syringomyelia
0 It is often characterized by CSF-filled cavitation in the cervical region.
0 Spinal cord tumors may develop after spinal cord hemorrhage and trauma.
0 If it progresses towards the bulbus, it is called syringobulbia.
Classic findings
1. Dissociated sensory loss in which the sense of pain and temperature is impaired (other senses intact)
2. Segmental weakening, weakness in hands and arms
3. Loss of tendon reflexes in the arms
0 May accompany Horner's syndrome (in the cervical segment).
0 May have developmental anomalies of the vertebral column (kypho-scoliosis, Feil syndrome)
0 Arnold-Chiari type 1 malformation is the most common syndrome of syringomyelia.
0 Hydromyelia: It is used to mean the cavitation of the central canal. Today, it is used in the same sense or as a subgroup of syringomyelia.
0 Diagnosis: MRI
0 In treatment: Syringotomy or centration
