男，16岁，于跆拳道训练中被打倒，头痛，颈项僵硬，行头颅CT和MRI扫描，被诊断为珠网膜下腔出血，怀疑为动脉瘤破裂所致。行16层CT扫描后三维重建，再次被诊断为颈内动脉动脉瘤。遂行血管内介入GDC栓塞动脉瘤。可是在脑血管造影过程中，各个角度反复造影，未发现动脉瘤。最后，在操作过程中原怀疑为动脉瘤的部位突然大出血，病人很快昏迷，急诊行血肿清除术。术中发现，可疑动脉瘤原来是颈内动脉破裂后形成的血肿，颈内动脉有一2mm的裂口，没有发现动脉瘤。(1)动脉瘤诊断的依据(2)不支持动脉瘤诊断的依据
参考答案：
(1)诊断依据：①活动时发病；②头痛，颈项僵硬；③CT提示颅底池高密度影；④颈内动脉岩上段高密度影；⑤三维重建提示颈内动脉岩上段囊性高密度影。
(2)不支持动脉瘤诊断的依据：①男性；②16岁；③MRI示可疑动脉瘤内无流空信号；④DSA示可疑动脉瘤包绕颈内动脉。
