目的 回顾性分析颌面部淋巴结外病变影响舌骨上颈动脉间隙的CT表现特点。方法 54例经活检和手术病理证实的影响舌骨上颈动脉间隙的颌面部病变分为颈动脉间隙组(Ⅰ组)和颈动脉间隙外组(Ⅱ组)。结果 Ⅰ组病变10例,均为良性。CT显示颈动脉间隙内血管移位者9例,病变与血管间脂肪带消失者3例。Ⅱ组病变44例,良性10例,恶性34例。CT显示病变压迫间隙内血管者14例(13例有血管移位),病变与血管间脂肪带消失者2例;病变包绕间隙内血管者30例(10例有血管移位),病变与血管间脂肪带均消失。结论 Ⅰ组病变对颈动脉间隙的影响主要是推移血管。Ⅱ组病变既可推移也可包绕颈动脉间隙内血管。
Objective To retrospectively analyze the CT features of maxillofacial lymph nodes affected the supra-lingual carotid gap. Methods Fifty-four patients with maxillofacial lesions of hyoid carotid gap confirmed by biopsy and surgical pathology were divided into carotid gap group (group Ⅰ) and carotid gap extraoral group (group Ⅱ). Results In group Ⅰ, 10 cases were all benign. CT showed vascular displacement in the carotid artery in 9 cases, lesions and vascular disappearance of fat in 3 cases. Ⅱ group of lesions in 44 cases, benign in 10 cases, 34 cases of malignant. CT showed that there were 14 vessels (13 vessels were translocated) in the interstitial space and 2 lesions disappeared in the blood vessel with the disappearance of the fat zone between the lesions. Thirty vessels (10 vessels had vascular displacement) surrounded the lesion, Vascular fat bands were disappeared. Conclusion The main influence of group Ⅰ disease on carotid artery gap is blood vessel. Ⅱ group of lesions can be passed around the carotid artery can also surround the blood vessels.
