Cavernous Malformation

  • Cavernous Malformation = cavernoma, cavernous angioma, cavernous hemangioma
  • Benign sporadic or familial low pressure vascular lesion with bleeding propensity
  • Locules of blood in different phases
  • 50% have calcification
  • show T2* GRE blooming artifact
  • Asymptomatic-Seizures,Major hemorrhage
  • Associated with developmental venous anomaly
