A rare spinal lesion, a brown tumor, caused nerve root compression and sciatica. This case highlights primary hyperparathyroidism as a potential cause of lumbar nerve root compression.

Area of Science:

  • Neurosurgery
  • Endocrinology
  • Pathology

Background:

  • Spinal tumors can present with neurological deficits.
  • Brown tumors are associated with hyperparathyroidism and are rarely found in the spine.

Observation:

  • A patient presented with sciatica due to a unilateral intraspinal cyst-like lesion at L4-L5.
  • Histological analysis revealed multinucleate giant cells, indicative of a brown tumor.

Findings:

  • The spinal lesion was identified as a brown tumor, a manifestation of primary hyperparathyroidism.
  • The lumbar nerve root compression was the initial clinical presentation of hyperparathyroidism.

Implications:

  • This case underscores the importance of considering metabolic bone diseases like primary hyperparathyroidism in the differential diagnosis of spinal tumors.

  • Early diagnosis and management of hyperparathyroidism are crucial to prevent neurological complications.
  • Radiological evaluation should include considerations for brown tumors in patients with spinal lesions and hyperparathyroidism.
