目的探讨慢性扩展性脑内血肿(CEICH)及合并隐匿性脑血管畸形(AOVM)的临床表现及影像学特征。方法回顾性分析CEICH21例患者的临床及影像学资料。结果21例CEICH均表现为脑内局灶性反复出血和扩展,14例合并有AOVM,其中部分病例CT扫描可见斑点状、条索状钙化,或显示点片状、条索状强化;MRI显示于出血灶内部或边缘可见等、低信号背景下密集杂乱小球形、斑点状高、等信号影。结论临床及影像学表现具有上述特点者,应考虑CEICH或合并AOVM,显微外科和病理检查是最佳确诊与治疗方法。
Objective To investigate the clinical manifestations and imaging features of chronic expandable intracerebral hematoma (CEICH) and complicated occult cerebrovascular malformation (AOVM). Methods The clinical and imaging data of 21 CEICH patients were retrospectively analyzed. Results All 21 cases of CEICH showed focal repeated hemorrhage and expansion in the brain, and 14 cases were complicated with AOVM. In some cases, CT scan showed spotted, cordlike calcification or patchy, cord-like enhancement; MRI showed Visible in the hemorrhage inside or edge, etc., under the background of low signal dense messy spherical, high spots, such as signal shadow. Conclusion Clinical and imaging findings with these characteristics should consider CEICH or combined AOVM, microscopic and pathological examination is the best diagnosis and treatment.
