摘要
目的:分析总结中枢神经系统海绵状血管瘤(CA)的临床和放射学特点及治疗效果。方法:回顾分析15年间收治的CA79例,其中颅内CA60例,眶内11例,椎管内8例。结果:本组平均病程4.3年,癫痫、局限性神经功能缺失,突眼和脊髓压迫症分别是上述部位CA的主要临床表现。CT多为高密度灶。MRT1W以混合信号为主;T2W高信号多见,部分瘤周可见环状低信号。肿瘤获全切者占79%,手术死亡率6%。47例平均随访5.6年,临床改善或无症状者占92%。结论:CA是生长缓慢的良性病变,手术治疗者效果较好;CT、尤其MR是诊断CA的最敏感方法。
Objective. To sdudy the clinical and radiological features and the therapeutic efficacy of cavernous angiomas (CA) in central nervous system. Methods: Retrospective analysis of 79 cases of CA treated in the last 15 years, including 60 intracranial cases, 11 intraorbital cases and 8 intraspinal canal cases were done. Results: The mean clinical course was 43 years. Seizures, focal neurological deficits, exophthalmos and spinal cord compression syndrome were the respective main presentation of CA in the above positions. CT showed high density lesions in most cases. MR T1W signal largely showed mixed signal intensity, T2W showed high signal intensity mostly, and the 'ring' sign of low T2 signal around CA could be seen in some cases. The tumors were totally removed in 79% of all the cases, and the operative mortality was 63%. Fourtyseven cases were followedup for average 56 years, 92% of them had clinical improvements or no symptoms. Conclusions: CA was a benign lesion which grow slowly. The results of management of these CA patients were good. CT, especially MR examination was the most sensitive method for diagnosis of CA.
