Syringomyelia

Syringomyelia is a chronic, progressive neurological disorder characterized by the development of a fluid-filled cavity (syrinx) within the parenchyma of the spinal cord. Over time, this cavity expands, compressing and damaging adjacent spinal cord tracts. This damage leads to a classic clinical presentation of dissociated sensory loss, muscle weakness, and autonomic dysfunction.

• Congenital: Most frequently associated with Chiari malformation Type I (herniation of cerebellar tonsils).
• Acquired: Spinal cord trauma, spinal tumors (e.g., ependymoma, hemangioblastoma), post-infectious meningitis, or arachnoiditis.
• Idiopathic: Rare cases with no identifiable cause.

Disruption of physiological cerebrospinal fluid (CSF) flow dynamics at the craniocervical junction or spinal canal redirects CSF under pressure into the spinal cord parenchyma. Fluid accumulates in the extracellular space or central canal, creating a syrinx. Longitudinal expansion and progressive dilation of the syrinx cause mechanical compression, ischemia, and subsequent gliosis of the decussating spinothalamic fibers in the anterior white commissure, followed by anterior horn cells and corticospinal tracts.

• Prevalence: Approximately 8.4 cases per 100,000 individuals.
• Age of Onset: Typically presents in young adulthood (ages 20 to 40).
• Gender Distribution: No significant gender predilection.

• Presence of Chiari malformations
• Prior spinal cord trauma or vertebral fractures
• Chronic spinal arachnoiditis
• Scoliosis or other spinal deformities

• Neurological Exam: Dissociated sensory loss (absent pain/temperature with preserved light touch and vibration) in a dermatomal distribution.
• Motor Exam: Lower motor neuron signs in upper extremities (muscle wasting, fasciculations, hyporeflexia); upper motor neuron signs in lower extremities (spasticity, hyperreflexia, extensor plantar responses).
• Autonomic Exam: Horner syndrome (miosis, ptosis, anhidrosis) if sympathetic pathways are compressed.

MRI of the Spine (Cervical/Thoracic): Purpose: Primary diagnostic modality. Typical Findings: Well-demarcated, intramedullary cavity matching CSF signal intensity (hypointense on T1, hyperintense on T2). Clinical Importance: Defines syrinx dimensions, localization, and detects associated pathology (e.g., Chiari malformation, spinal tumors).
Cine-MRI (Phase-Contrast): Purpose: Evaluate CSF flow dynamics. Typical Findings: Abnormal CSF flow patterns at the craniocervical junction. Clinical Importance: Aids in surgical planning and assessing postoperative decompression success.

• Amyotrophic Lateral Sclerosis (ALS): Lacks sensory deficits.
• Multiple Sclerosis (MS): Characterized by demyelinating plaques separated in time and space on MRI.
• Cervical Spondylotic Myelopathy: MRI shows osteophytic compression of the cord without an internal cavity.
• Spinal Cord Astrocytoma/Ependymoma: MRI shows enhancing nodular components, unlike a benign syrinx.

• Neuropathic (Charcot) joints
• Chronic, severe central pain syndrome
• Recurrent aspiration pneumonia (due to dysphagia in syringobulbia)
• Permanent paraplegia or quadriplegia

• Untreated: Often slowly progressive, leading to severe neurological disability and wheelchair dependence.
• Surgical Prognosis: Decompression stabilizes or improves symptoms in 50% to 80% of patients. Long-standing sensory deficits or muscle atrophy are less likely to reverse completely.

• Early surgical correction of symptomatic Chiari malformations.
• Prompt decompression and stabilization of spinal fractures.
