摘要
目的探讨丘脑胶质瘤的影像学特征与手术入路的选择。方法回顾性分析我科显微手术治疗的20例丘脑胶质瘤的影像学特征、手术入路及术后情况。结果术前MRI提示肿瘤主体位于丘脑外侧近岛叶2例,位于丘脑后外侧18例;内囊后肢位于肿瘤前外侧方16例,侧方4例。本组经外侧裂岛叶入路2例,经颞-侧脑室入路6例,经颞顶或顶枕-侧脑室三角区入路12例。肿瘤全切除14例,次全切除3例,大部分切除3例。术后症状改善11例,无明显变化5例,症状加重4例。随访2个月~1年,肿瘤复发2例。结论显微手术是治疗丘脑胶质瘤的有效手段,肿瘤位置、生长方式及瘤体与内囊后肢的关系有助于个体化制定手术入路和切除范围。
Objective To analyze the imaging features and surgical approaches of thalamic gliomas. Methods A retrospective study was performed in 20 patients with thalamic gliomas whom were received microsurgery. We analyzed the clinical data of all patients and draw some clinical experiences. Results Two tumors located lateral of thalamus and were close to the insular cortex, 18 tumors located lateral of thalamus posterolateral. The posterior limb of the internal capsule （PLIC）, based on T2- weighted magnetic resonance axial sections, was displaced anterolaterally in 16 cases and laterally in 4 cases. The transylvian trans-insular approach was used for 2 cases, the temporal cortex-lateral ventricle surgical approach was used for 6 cases, the temporoparietal or parietal--occipital surgical approach were used for 12 cases. In this series,total resction of the tumor was 14 cases, subtotal 3 cases, partial 3 cases. Post operative improvement was achieved in 11 cases, stabilization in 5 cases, aggravation in 4 cases. In addition, tumor recurrence was found in two patients during follow--up. Conclusion Mierosurgery is an effective method for treatment of thalamic gliomas. The appropriate surgical approach should be based on their location,growth pattern and the displacement of the PLIC.
