    A rare angiosarcoma developed in the thoracic spinal cord years after chordotomy surgery. This spinal cord tumor caused paraplegia and a sensory lesion, highlighting a potential link between prior surgery and tumor development.

    Area of Science:

    • Neuropathology
    • Oncology
    • Neurosurgery

    Background:

    • Chordotomy is a surgical procedure to relieve intractable pain.
    • Spinal cord tumors can cause significant neurological deficits.

    Observation:

    • A 60-year-old male developed acute paraplegia and sensory loss 5 years post-chordotomy.
    • An extradural tumor at the thoracic (Th) 1-4 level was identified.
    • Neuropathology revealed transverse necrosis of the thoracic spinal cord (Th 1-4).

    Findings:

    • The thoracic malignancy arose at the site of previous chordotomy, with a suture found within the tumor.
    • Histology and immunostaining (Factor VIII antigen) suggested angiosarcoma.
    • Ultrastructural analysis showed Weibel-Palade bodies, confirming endothelial origin.

    Implications:

    • This case suggests a rare association between prior chordotomy and the development of intraspinal angiosarcoma.
    • The findings warrant further investigation into the potential iatrogenic origins of spinal meningeal tumors.
    • Understanding this link is crucial for neurosurgical risk assessment and patient monitoring.
