Imaging signs for predicting hematoma enlargement in patients with intracerebral hemorrhage / 国际脑血管病杂志

Hematoma enlargement is a common harmful event after cerebral hemorrhage, which can lead to deterioration of neurological function and poor outcome. Early detection of high-risk patients can help prevent hematoma enlargement and improve the outcome of patients. Although the exact mechanism of hematoma enlargement is unclear, more and more evidence shows that many imaging signs may be related to hematoma enlargement, such as dot sign, mixed sign, black hole sign, island sign, etc. This article mainly reviews the relevant imaging prediction factors of hematoma enlargement from the perspective of imaging.
