T1WI에서는 약간 heterogeneous isosignal intensity를 보이고 조영증강은 거의 관찰되지 않음. Spinal cord cavernous malformation Vascular lesion with lobulated, thin sinusoidal vascular channels, no interspersed neural tissue Locules of blood with fluid-fluid levels surrounded by very T2 hypointense rim Location ; spinal cord uncommon site, 3-5% of all cavernous malformation - Thoracic (50%) - Cervical (40%) - Conus (10%) Round heterogenous signal abnormality, well-defined margins T2WI - Heterogeneous (blood products, varying ages) - No edema, unless recent hemorrhage T1WI C+ ; enhancement absent/minimal Calcification ; rare (common in brain cavernous malformation) Bleeding rate ; 1-5% |
