Cerebral Hemorrhage

Last Updated: October 1, 2018

Figure 1: There is a moderate sized lesion in the right thalamus with T1 isointense signal (top row left), heterogeneous isointense and hyperintense signal on FLAIR (top row right) with associated susceptibility artifact centrally on SWI (middle row left). Note that there is a mild amount of reduced diffusivity which in this cases is likely due to the susceptibility artifact from the hemorrhage on DWI/ADC (middle row right, bottom row left). Enhancement may be present in the periphery as in this case (bottom row right), particularly in the subacute stage. Notice that the age of the blood products is not clear by signal intensities. Often the signal characteristics are heterogeneous, as is seen in this case, making accurate staging difficult and potentially inaccurate.
