Area of Science:

  • Neurology
  • Pathology
  • Surgical Oncology

Background:

  • Intravascular papillary endothelial hyperplasia (IPEH) is a rare vascular proliferation.
  • IPEH rarely affects the neuraxis, with limited reported cases of spinal involvement.

Observation:

  • A 17-year-old male presented with neurological deficits including pain, numbness, paresis, and bladder dysfunction.
  • Spinal imaging revealed a T12-L1 intraspinal tumor causing cauda equina compression.

Findings:

  • Surgical exploration identified a red nodular epidural tumor.
  • Pathological examination confirmed the diagnosis of intravascular papillary endothelial hyperplasia.
  • Complete tumor resection resulted in significant neurological recovery and symptom resolution.

Implications:

  • IPEH can mimic malignant vascular tumors like angiosarcoma, necessitating accurate histopathological diagnosis.
  • Complete surgical resection is curative for IPEH, preventing misdiagnosis and unnecessary aggressive treatments.
