目的探讨CT诊断和显微手术治疗在恶性脑膜瘤诊治中的临床价值。方法结合文献,回顾性分析我院2000年1月—2007年1月收治的行CT检查并经显微手术治疗及病理证实的恶性脑膜瘤患者29例。结果29例恶性脑膜瘤包括脊索样型1例、非典型7例、透明细胞型1例、间变型20例,显微外科手术SimpsonⅠ级11例,Ⅱ级6例,Ⅲ级11例,Ⅳ级1例。结论恶性脑膜瘤临床表现无特异性,CT检查有助于诊断,显微手术全切者预后优于部分切除,辅以术后放疗可有效降低复发率。
Objective To investigate the clinical value of CT diagnosis and microsurgical treatment in the diagnosis and treatment of malignant meningioma. Methods Combined with the literature, 29 patients with malignant meningioma confirmed by microsurgical treatment and pathology were retrospectively analyzed in our hospital from January 2000 to January 2007. Results The 29 cases of malignant meningiomas included 1 chordal type, 7 atypical type, 1 clear cell type, 20 anaplastic type, 11 microsurgical Simpson grade Ⅰ, 6 grade Ⅱ, 11 grade Ⅲ, Ⅳ grade 1 case. Conclusions The clinical manifestations of malignant meningioma are nonspecific. CT examination is helpful for the diagnosis. The prognosis of the patients undergoing microsurgical resection is better than that of partial resection. The adjuvant radiotherapy can effectively reduce the recurrence rate.
