MRI of Intramedullary Spinal Cord Cavernoma

General Findings

  • Average size is 1 cm or less in diameter.
  • Fresh hemorrhage may be present.
  • Venous angioma may be present.

T1-Weighted Sequence

  • Hyperintense centrally with varying levels of intensity reflecting past hemorrhages of varying duration.
  • Hypointense halo surrounds the hyperintense core.  This is due to hemosiderin (21).

T2-Weighted Sequence

  • Hypointense central core with scattered small areas of hyperintensity.
  • Hyperintense halo due to hemosiderin is larger that halo seen on T1-weighted sequneces.
