[Spasmodic torticollis and vertebral hemangioma]

Area of Science:

• Neurology
• Spinal Cord Disorders
• Dystonia

Background:

• Spasmodic torticollis in young patients often indicates an underlying primary disorder.
• Diagnostic evaluation is crucial before labeling torticollis as idiopathic.

Observation:

• A 30-year-old male with a history of writer's cramp and spasmodic torticollis presented with neurological findings including absent arm reflexes and limited neck rotation.
• Spinal imaging revealed a T1 hemangioma, a vascular malformation, which was the likely cause of the cervical dystonia.
• Despite extensive investigations, the hemangioma's vascular supply precluded surgical or interventional treatment.

Findings:

• A T1 spinal hemangioma was identified as the cause of secondary spasmodic torticollis.
• Cervical spinal cord alterations can lead to focal dystonia through increased motor neuron excitability.
• Dysfunction in descending inhibitory pathways may contribute to the development of dystonia.

Implications:

• This case underscores the necessity of thorough diagnostic workups for spasmodic torticollis to identify secondary causes.
• Spinal cord abnormalities should be considered in the differential diagnosis of focal dystonia.
• Understanding the pathophysiology of cervical spinal cord alterations is key to managing secondary torticollis.
