目的总结颅内海绵状血管瘤的临床表现、影像学特点及治疗结果。方法分析8年间收治的颅内海绵状血管瘤40例患者的临床资料。结果本组平均病程28个月。颅内海绵状血管瘤的主要表现为头痛、癫痫发作、视力减退及局灶性功能障碍。CT:较小的病灶多无阳性发现。核磁共振:瘤周可见低信号环。脑血管造影(DSA)检查:无血管占位征像。开颅手术治疗40例,随访6个月~7年。能正常工作32例,占80%,生活能自理8例,占20%。无死亡及复发。结论颅内海绵状血管瘤是生长缓慢的先天性脑血管畸形,以手术治疗效果为好,术中超声有助于颅内海绵状血管瘤的准确定位,提高手术的准确性和安全性。
Objective To summarize the clinical manifestations, imaging features and treatment results of intracranial cavernous hemangiomas. Methods The clinical data of 40 patients with intracranial cavernous hemangiomas admitted in 8 years were analyzed. Results The average duration of 28 months in this group. The main manifestations of intracranial cavernous hemangiomas are headache, seizures, vision loss and focal dysfunction. CT: Small lesions and no positive findings. Nuclear magnetic resonance: visible low signal ring tumor. Cerebral angiography (DSA) examination: No vascular placeholder signs. Craniotomy 40 cases were followed up for 6 months to 7 years. 32 cases can work normally, accounting for 80%, 8 cases of life can take care of themselves, accounting for 20%. No death or relapse. Conclusion Intracranial cavernous hemangioma is a slow-growing congenital cerebrovascular malformation. Surgical treatment is preferable. Intraoperative ultrasound can help the accurate localization of intracranial cavernous hemangiomas and improve the accuracy and safety of the operation.
