Spontaneous chronic spinal subdural hematoma associated with spinal arachnoiditis and syringomyelia

Abstract:
Spontaneous chronic spinal subdural hematoma is rare. We describe a case of spontaneous chronic spinal subdural hematoma associated with arachnoiditis and syringomyelia in a 76-year old woman who presented with a 14-year history of progressive myelopathy. MRI scan revealed a thoraco-lumbar subdural cystic lesion and a thoracic syrinx. The patient underwent thoracic laminectomy and decompression of the lesion, which was a subdural hematoma. A myelotomy was performed to drain the syrinx. Pathological examination revealed features consistent with chronic subdural membrane. This report attempts to elucidate the pathogenesis of chronic spinal subdural hematoma. We discuss possible etiological factors in light of the current literature and pathogenesis of both spinal subdural hematoma and syrinx formation.
Insights
Spontaneous chronic spinal subdural hematoma, a rare condition, can occur with arachnoiditis and syringomyelia. This case highlights a 76-year-old woman with a 14-year history of myelopathy, successfully treated with surgery.
Area of Science:
- Neurosurgery
- Neurology
- Pathology
Background:
- Spontaneous chronic spinal subdural hematoma (CSDH) is an uncommon neurological condition.
- CSDH can present with progressive myelopathy, mimicking other spinal cord pathologies.
- Association with arachnoiditis and syringomyelia is rarely reported.
Observation:
- A 76-year-old woman presented with a 14-year history of progressive myelopathy.
- Magnetic Resonance Imaging (MRI) revealed a thoraco-lumbar subdural cystic lesion and a thoracic syrinx.
- Surgical intervention included laminectomy, decompression of the subdural hematoma, and myelotomy for syrinx drainage.
Findings:
- Pathological examination confirmed a chronic subdural membrane.
- Surgical decompression and syrinx drainage led to clinical improvement.
- The case provides insight into the pathogenesis of spinal subdural hematoma and syrinx formation.
Implications:
- This case underscores the importance of considering CSDH in patients with chronic myelopathy.
- Understanding the pathogenesis may aid in earlier diagnosis and treatment of CSDH and associated syringomyelia.
- Further research into etiological factors is warranted to elucidate the development of CSDH.
