Perihematomal edema (PHE) has been represented as an important secondary injury after intracerebral hemorrhage (ICH). The evolution of PHE contributed to mass effect, which could induce the increase of intracranial pressure. The volume of PHE increased rapidly in the early stage of ICH and continued to increase for 7 to 11 days after symptom onset, and the edema extension distance (EED) increased rapidly within 24 hours, accounting for 60% of the peak EED [1-2]. For the timepoint of follow-up CT scans was different, the fastest development stage of PHE could also be 48 or 72 hours after symptom onset [3-4]. If patients with ICH could not benefit from early surgical evacuation of the hematoma, anti-edema treatment may bring better therapeutic effect. Thus, the use of anti-edema treatment may need to be considered for reducing PHE volume during the early phase of PHE development. How to appropriately predict PHE growth is important in patients at the early stage of ICH.
