了解侵入颅内颅骨肿瘤的临床表现、放射学表现和治疗方法，增加对此类疾病的认识，减少误诊率，提高诊疗水平。材料和方法：搜集1986－1996年间经手术和病理证实的35例颅骨肿瘤（包括肿瘤样变），观察分析其临床表现、X线、CT和MRI放射学表现，并评价手术、放疗对预后的影响。结果：术前X线平片、CT、MRI三者定位准确率分别为93％、95％和100％，综合定位准确率100％，定性准确率91％，误诊3例，占9％。结论：由于肿瘤生长部位不同，临床表现也各异。头颅X线平片、CT、MRI三者结合综合分析对颅骨肿瘤具有定位定性作用。X线平片可作为颅骨肿瘤诊断的首选检查，MRI则能清楚显示肿瘤的生长方式以及肿瘤与邻近解剖结构的关系。手术治疗效果好，部分肿瘤术后放疗可加强疗效。
Understand the clinical manifestations of invasive intracranial skull tumors, radiological manifestations and treatment methods to increase awareness of such diseases, reduce the misdiagnosis rate and improve the level of diagnosis and treatment. MATERIALS AND METHODS: Thirty-five skull tumors (including tumor-like lesions) confirmed by operation and pathology from 1986 to 1996 were collected. The clinical manifestations, radiographic findings of X-ray, CT and MRI were observed and evaluated. influences. Results: The accuracy of preoperative X - ray, CT and MRI positioning was 93%, 95% and 100% respectively. The accuracy of comprehensive positioning was 100%, the accuracy rate was 91%, misdiagnosis was 9% and 9%. Conclusion: Due to the different tumor growth sites, clinical manifestations are also different. Skull X-ray, CT, MRI combined comprehensive analysis of the three cranial tumors with qualitative positioning. X-ray film can be used as the first choice for the diagnosis of skull tumors, MRI can clearly show the growth of tumor and the relationship between tumor and adjacent anatomy. Surgical treatment is effective, some of the tumor after radiotherapy can enhance the efficacy.
