A rare bone amyloidoma in the upper thoracic spine caused spinal cord compression. This calcified mass originated in the second rib and invaded the spine.

Area of Science:

  • Medical Imaging
  • Oncology
  • Neurosurgery

Background:

  • Primary bone amyloidoma is an exceptionally rare condition.
  • Spinal cord compression can result from various pathologies, including tumors and masses.

Observation:

  • This case details a localized primary bone amyloidoma presenting as a rare cause of upper thoracic spinal cord compression.
  • Imaging modalities including myelography, computed tomography (CT), and magnetic resonance (MR) were utilized.

Findings:

  • A large, calcified mass was identified.
  • The mass was centered in the posteromedial aspect of the left second rib.
  • The tumor invaded the second thoracic vertebra and the spinal canal.

Implications:
