目的 :探讨中颅凹底巨大海绵状血管瘤的诊断和治疗方法。方法 :9例中颅凹底巨大海绵状血管瘤 ,行额颞开颅去骨瓣减压术 ,全切除 4例 ,部分切除 1例 ,活检 4例 ,活检中 2例 +部分切除 1例行放射治疗。结果 :无手术死亡。随访期 9个月～ 11 5年 ,4例全切除者无肿瘤复发 ,3例放疗者肿瘤消失 ,未治疗者 2例无变化。结论 :肿瘤放疗和人工栓塞可以增加手术全切除率。放疗对巨大海绵状血管瘤有效 Objective: To investigate the diagnosis and treatment of giant cavernous hemangiomas in the midcave. Methods: Nine cases with giant cavernous hemangioma in the middle of the esophagus were treated with frontotemporal craniotomy and decompressive craniectomy. Four cases were totally excised, one partial excision and four biopsies. Two biopsies and one partial excision were performed Radiation Therapy. Results: No operative death. During the follow-up period of 9 months to 115 years, no tumor recurrence was found in 4 cases of total resection and no tumor was found in 3 cases of radiotherapy. No change was found in 2 cases of untreated group. Conclusion: Tumor radiotherapy and artificial embolization can increase the total resection rate. Radiotherapy is effective on giant cavernous hemangiomas
