Cerebral Microhemorrhages Associated with Favorable Hematoma Characteristics in Intracerebral Hemorrhage

Although many patients who present with intracerebral hemorrhage (ICH) also have signs of cerebral small vessel disease such as white matter hyperintensities and cerebral microhemorrhages (CMBs) on imaging, the precise relationships between small vessel disease and ICH are not straightforward. For example, multiple studies have found a higher incidence of ICH in patients with CMBs, but data on whether CMBs predict acute hematoma characteristics for these incident ICHs, such as hematoma volume or hematoma expansion, are conflicting. To further explore these potential relationships, investigators pooled data from 1499 patients with supratentorial ICH enrolled in two large international trials.

Since MRI scans were specified by the study protoc…
