Blood Crust

  • Blood clots typically appear as primarily hyporeflective amorphous structures presenting with a heterogeneous texture, a combination of hyperreflective speckle and areflective spaces


  • Unlike keratin plaques blood clots, while having a similar appearance, do not cause distinct bands of shadow but in some cases may produce a diffuse shadow on lower layers


  • Blood clots beneath the surface have the same presentation to surface clots with the typical heterogeneous texture and predominately hyporeflective appearance
  • Absence of perfusion and blood flow also define clotted areas
