目的：探讨小脑海绵状血管瘤的影像学表现，诊断和病理学特点。方法：回顾性研究我院10年间进行显微手术治疗且病理证实为小脑海绵状血管瘤15例患者的临床资料，并对其进行分析。结果：14例急性起病，表现为小脑自发性出血。其中有1例以共济失调为表现慢性起病。头 MRI 平扫与增强多表现为 T1高信号，T 2高或混杂信号，病灶周围有环形低信号带。磁敏感加权成像序列（SWI）更有助于诊断。结论：自发性出血是本病的主要症状，多有共济失调等小脑受损体征。 MRI 具有较高的诊断特异性。%Objective :Cerebellar cavernous malformation was comparatively rare in intracranial vascular malformation with a lower incidence .This paper discusses the imaging findings ,diagnosis ,pathology .Methods :Retrospective study of nearly 15 years in our hospital 15 patients with pathological diagnosis for patients with cere‐bellar cavernous malformation cases ,who underwent surgical treatment ,according to the imaging findings ,patho‐logical diagnosis and prognosis were analyzed carefully .Results :14 cases had acute onset ,with the symptom of cere‐bellum hemorrhage ,1 case had chronic onset ,with the signs of progressive ataxia .T1 WI shows low or equal signal ;T2 WI shows non‐homogeneous high and mixed signal with a surrounding hypointense rim ,susceptibility‐weighted imaging (SWI) increase the diagnostic specificity and sensitivity of cerebella cavernous malformation .Conclusions :Spontaneous hemorrhage is the main symptoms of cerebellar carvernous malformation ,which with the signs of cere‐bellum damage as ataxia .MRI has a high differential and sensitivity .
