Abstract 【Objective】To investigate the CT imaging features of hematoma enlargement in early stage of spontaneous intracerebral hemorrhage and its value in predicting early hematoma enlargement. 【Methods】Forty-two patients with spontaneous intracerebral hemorrhage diagnosed by head CT in two hospitals from February 2023 to February 2024 were selected and divided into expanded hematoma group (n=28) and unexpanded hematoma group (n=14) according to the changes of early hematoma. The imaging features of early expanded hematoma in patients with spontaneous intracerebral hemorrhage and the influencing factors of early expanded hematoma in patients with spontaneous intracerebral hemorrhage were analyzed. 【Results】The detection rate of island sign and mixed sign in patients with enlarged hematoma was significantly higher than that in the group without enlarged hematoma (P<0.05). Logistic regression analysis showed that island sign, mixed sign, island sign and mixed sign were independent predictors of early hematoma enlargement in patients with spontaneous intracerebral hemorrhage (P<0.05). The sensitivity and specificity of island sign to predict early hematoma enlargement were 53.57% and 85.71% respectively. The sensitivity and specificity of mixed signs in predicting early hematoma enlargement were 85.71%. The sensitivity and specificity of island sign and mixed sign were 89.29% and 92.86% respectively. The sensitivity and specificity of both island sign and mixed sign were higher than those of island sign and mixed sign in predicting early hematoma enlargement. 【Conclusion】The prediction value of island sign and mixed sign is higher for early hematoma enlargement in patients with spontaneous intracerebral hemorrhage, but the prediction value of island sign and mixed sign is higher, which can provide important reference for clinicians.
