Pediatric Vertebral Hemangioma

• Etiology: Venous malformation
• Imaging: Usually in thoracic spine
• Imaging CT:
  — Axial CT shows polka dot or salt and pepper appearance due to thickened vertebral trabeculae
  — Sagittal CT shows corduroy sign due to thicker vertical trabeculae
• Imaging MRI:
  — T1WI: Typical lipid-rich hemangioma has high signal while atypical lipid-poor hemangioma has low signal
  — T1WI post contrast: Significant enhancement due to high vascularity
  — T2WI: Bright signal usually greater than on T1 due to high water content
• DDX:
• Complications:
• Treatment: Usually not necessary
• Clinical: Usually asymptomatic and noticed incidentally
