35例累及颈动脉间隙病变的影像分析

Imaging analysis of thirty-five patients with carotid space were involved

目的:探讨邻近或转移性病变累及颈动脉间隙的影像特点。方法:搜集35例疾病经临床病理证实患者的影像资料,分析其病变累及颈动脉间隙的影像学表现。结果:转移性淋巴结20例(占57%)均推压、包绕颈动脉间隙内血管。淋巴瘤7例(占20%)均为推移颈动脉间隙内血管。其他病变(8例,占23%)如神经鞘瘤等均以推压为主,使颈动脉间隙内血管移位。10例恶性肿瘤及1例病灶感染(占31%)则表现为病变与血管之间的脂肪层消失。结论:转移性淋巴结多为包绕颈动脉间隙内的血管。淋巴瘤及良性肿块主要是推移颈动脉间隙内的血管。

Aim： To analyze retrospectively the imaging features of neighbouring and metastatic lesions which involved carotid space. Methods： Thirty-five patients with neck lesions （included lymph nodes） proven by clinical pathology, analyzed their imaging manifestation which involved carotid space, Results： Twenty cases of metastatic lymph nodes （57%）showed displace and encompassment blood vessel of carotid space. Seven cases （20%） of lymphoma showed displace blood vessel of carotid space. Others （ eight case, 23% , neufilemmoma, and so on） showed displace blood vessel of carotid space. The fat septa vanished （31% ） between lesions and blood vessel in twelve malignancy lesions and one lesion. Conclusion： Metastatic lymph nodes show encompassment of blood vessel in carotid space. Lymphoma and benign lesions appear displace blood vessel in carotid space.
