目的 分析小脑出血的CT影象及临床表现.方法 对48例小脑出血患者的发病原因、临床症状、CT表现、治疗方法及转归进行回顾性分析.结果 本病多见于老年患者(＞60岁),以高血压动脉硬化为丰要病因,中青年患者(＜40岁)多以动静脉畸形为主要病因.临床表现主要为头痛、呕吐、共济失调、语言障碍.预后与出血量、出血部位、血肿是否破入第四脑室及脑干是否受压密切相关.结论 小脑出血的CT诊断分析要重视出血部位、出血量、脑室受累和占位效应.出血量少者预后好,出血量＞15ml的预后不良.且出血量大的应及早采用手术治疗.%Objective To analyze cerebellar hemorrhage in the CT and clinical manifestations. Methods To analyze pathogenesis, cltnical symptoms, CT manifestations, treat-ment and prognosis of 48 patients with cerebellar hemorrhage retrospectively. Results The disease was particularly prevalent in elderly patients (More than 60-year-old) and Hyperten-sive arteriosclerosis is the main cause of the disease. To many young and middle-aged patients (Less than 40-year-old) ,Arteriovenous malformations is the main cause. The main clinical manifestations were headache, vomiting, ataxia, speech impairment. Prognosis is closely related to the amount of bleeding, bleeding site, hematoma is breaking into the fourth ventricle, and brainstem compression. Conclusion Cerebellar hemorrhage in the CT diagnosis of attention should be paid to bleeding site, bleeding volume, ventricle involvement, mass effect. Less bleeding leads to good prognosisand the amount of bleeding is greater than 15 milliliters leads to poor prognosis.
