Malignant invasion of the carotid artery is an ominous complication of squamous cell carcinoma that can be suspected from B-mode sonography. A loss of carotid wall integrity seen as a break or step off of the inner wall suggests early involvement. Frank tumor invading the lumen is an end-stage event. Both ultrasound and magnetic resonance imaging are 100% sensitive in the evaluation that no carotid involvement has occurred. In one study, ultrasound was 75% specific and magnetic resonance was 87.5% specific. If the ultrasound is problematic, magnetic resonance may clarify the issue.
颈动脉的恶性侵犯是鳞状细胞癌的一种不祥并发症,可通过B超检查怀疑。颈动脉壁完整性丧失表现为内壁的中断或台阶状,提示早期受累。肿瘤明显侵入管腔是终末期表现。超声和磁共振成像在评估未发生颈动脉受累方面的敏感性均为100%。在一项研究中,超声的特异性为75%,磁共振的特异性为87.5%。如果超声检查结果不明确,磁共振可能会澄清问题。
