Paraneoplastic subacute necrotic myelopathy
Summary
This case report describes a rare instance of paraneoplastic subacute necrotic myelopathy in a patient with renal cell carcinoma. The condition presented as Brown-Sequard syndrome, leading to progressive spinal cord damage.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Renal cell carcinoma (RCC) resection can rarely be followed by neurological complications.
- Brown-Sequard syndrome is a rare neurological condition characterized by unilateral spinal cord damage.
Observation:
- A 79-year-old male developed Brown-Sequard syndrome two weeks post-RCC resection.
- The patient experienced subacute progression of spinal cord signs.
- Pathological examination revealed extensive multifocal spinal cord necrosis.
Findings:
- The spinal cord necrosis was not attributable to vascular occlusion or vasculitis.
- The findings suggest a paraneoplastic etiology for the myelopathy.
- This represents a rare case of paraneoplastic subacute necrotic myelopathy.
Implications:
- This case highlights a rare neurological complication associated with renal cell carcinoma.
- It underscores the importance of considering paraneoplastic syndromes in patients with unexplained neurological deficits post-cancer surgery.
- Further research into the mechanisms of paraneoplastic myelopathy is warranted.
