A rare case of focal vertebral osteonecrosis without collapse was reported. Imaging showed specific MRI findings, aiding diagnosis of this uncommon condition.

Area of Science:

  • Radiology
  • Pathology
  • Orthopedic Surgery

Background:

  • Focal vertebral body osteonecrosis without collapse is an exceptionally rare condition.
  • No prior literature describes this specific presentation.

Observation:

  • A case report and literature review were conducted.
  • Idiopathic focal vertebral osteonecrosis without collapse was identified.

Findings:

  • Computed tomography revealed sclerotic changes.
  • Magnetic resonance imaging demonstrated T1 low intensity, T2 high intensity with clear margins, and absent gadolinium enhancement.
  • Bone scan showed no uptake.
  • Histopathology confirmed bone marrow necrosis with empty lacunas and fatty degeneration.

Implications:

  • Vertebral body osteonecrosis should be considered in the differential diagnosis for patients with characteristic MRI findings.
  • These imaging features can aid in the diagnosis of focal vertebral osteonecrosis.
  • Understanding these features is crucial for appropriate patient management.
