Representative cases. T2*-weighted MR image (A) and CT scan (B) in an 84-year-old patient. Recurrent right cerebellar hemorrhage (arrow) corresponds to the location of MBs detected 9 months before (arrowhead). T2*-weighted MR image (C) and CT scan (D) in an 80-year-old patient. Recurrent left thalamic hemorrhage (arrow) corresponds to the location of MBs detected 35 months before (arrowhead). T2*-weighted MR image (E) and CT scan (F) in an 85-year-old patient. Recurrent left lobar hemorrhage (arrow) corresponds to the location of MBs detected 3 months before (arrowhead).

Correspondence of MBs in each part of the hematoma. The correspondence ratio was higher in the deep ICH group, particularly in thalamic and putaminal hemorrhage, than in the lobar ICH group.
