目的 分析新生儿脑梗死的临床和CT表现，提高其诊断与鉴别诊断水平。方法 回顾性分析27例新生儿脑梗死的临 床和CT资料。结果 左侧脑梗死15例，占55.6%，右侧6例，占22.2%，双侧6例，占22.2%；发生于顶枕叶20例，占 74.1%；大脑中动脉供血区受累25例，占92.6%；CT表现呈底朝外的楔形或扇形低密度，灰白质同时受累，病灶边缘 部分清楚，病变区脑沟变浅或消失，周围水肿较轻，中线结构轻度移位。结论 新生儿脑梗死临床表现无特异性， CT检查是诊断新生儿脑梗死的重要手段。

Objective To analyze the clinical and CT manifestations of neonatal cerebral infarction, and to improve the level of diagnosis and differential diagnosis of neonatal cerebral infarction. Methods Retrospective analyze the clinical and CT data of 27 cases with neonatal cerebral infarction. Results There were 15 cases of cerebral infarction located on the left hemicerebrum (55.6%); 6 cases located on the right hemicerebrum (22.2%); 6 cases located on bilateral hemicerebrum (22.2%). 20 lesions were in occipital lobe (74.1%); Middle cerebral arteries were involved in 25 lesions (92.6%). In the CT images, the lesions were shown as low density wedge or sector shapes with bottom outlying, with gray matter affected at the same time. The edges of the lesions were clear, with the brain ditch shoaled or disappeared. The peripheral edema was lighter. The midline structures were slightly shifted. Conclusion The clinical manifestations of neonatal cerebral infarction were lack of specificity, and CT examination is an important method for diagnosis of neonatal cerebral infarction.
