目的:探讨影像学诊断颅底脊索瘤影像分析的临床应用价值。方法:自2014年9月到2015年4月收集的13例颅底脊索瘤患者,对其拟诊CT以及MR影像进行分析。结果:本次收集到的病例比较典型,13例颅底脊索瘤患者,以中老年患者为主,男女发病率大致相当,临床表现以头痛为主,部分病例出现颅底神经受累表现及锥体束受累症状,其中年纪较小的病例患者无明显临床表现,只是偶然CT检查发现。患者病程较长,在2个月-10年,平均3年,进一步支持颅底脊索瘤病灶呈缓慢浸润性生长特点。其中有一列临床最后确诊为鼻咽癌侵及颅底斜坡外,其它病例经过病理检查确诊为颅底脊索瘤。结论:分析总结颅底脊索瘤影像诊断要点,提高诊断水平,相应做出影像学分析,体现出临床应用价值。
Objective: To explore the clinical value of imaging diagnosis of skull base chordoma image analysis. METHODS: Thirteen patients with skull base chordoma collected from September 2014 to April 2015 were enrolled in this study. Their CT and MR images were analyzed. Results: The collected cases were typical. 13 cases of patients with skull base chordoma were mainly middle-aged and elderly patients. The incidence of men and women was roughly the same. The main clinical manifestations were headache. In some cases, the manifestations of skull base nerve involvement and cones Bunch affected symptoms, including younger patients with no significant clinical manifestations, only by accidental CT examination found. Patients with longer duration, in 2 months - 10 years, an average of 3 years, further support for skull base chordoma lesions were slowly invasive growth characteristics. One of the last clinically diagnosed cases of nasopharyngeal carcinoma invading the skull base slope, the other cases after pathological examination diagnosed as skull base chordoma. CONCLUSION: The main points of imaging diagnosis of skull base chordoma are summarized and analyzed, and the imaging diagnosis is analyzed accordingly. The clinical value is demonstrated.
