Abstract:
We describe a 31-year-old diabetic man, with granulomatous angiitis confined to the spinal cord, who developed rapidly progressive spastic paraplegia, clinically interpreted as being secondary to a spinal cord infarct. At the time of autopsy, vasculitis was limited to the spinal cord, without involvement of cerebral vessels. The inflammatory cells were predominantly CD4+ T lymphocytes, with few CD8+ T and B lymphocytes. The phenotypical composition of the inflammatory infiltrate is similar to that described in other granulomatous disorders such as sarcoidosis and tuberculin reaction.
Insights
A diabetic man experienced rapid leg weakness due to granulomatous angiitis affecting only his spinal cord. Autopsy revealed vasculitis limited to the spinal cord, with CD4+ T cells as the primary inflammatory cells.
Area of Science:
- Neurology
- Immunology
- Pathology
Background:
- Granulomatous angiitis is a rare inflammatory condition affecting blood vessels.
- Spinal cord involvement can lead to severe neurological deficits.
Observation:
- A 31-year-old diabetic male presented with rapidly progressive spastic paraplegia.
- Clinical diagnosis suggested a spinal cord infarct.
Findings:
- Autopsy revealed granulomatous vasculitis confined exclusively to the spinal cord.
- The inflammatory infiltrate was predominantly composed of CD4+ T lymphocytes.
- This cellular profile resembles that seen in sarcoidosis and tuberculin reactions.
Implications:
- This case highlights spinal cord-limited granulomatous angiitis as a cause of progressive spastic paraplegia.
- Understanding the inflammatory profile may aid in diagnosing similar rare conditions.
- Further research into the pathogenesis of spinal cord-specific vasculitis is warranted.
