摘要
目的 :探讨颈动脉鞘区肿块的CT特征及其定性诊断的价值。方法 :对经手术和病理证实的 2 1例颈部肿块作回顾性分析。结果 :6例神经鞘瘤中 5例使血管移位 ,呈斑驳样强化。 1例呈囊性改变血管未见移位。 2例神经纤维瘤病1例可见血管移位 ,呈低密度 ,未见强化。 1例颈动脉体瘤位于颈动脉分叉处 ,有血管移位。 1例颈动脉瘤呈囊状扩张伴有假性囊肿的形成。转移瘤多有中央坏死 ,部分可见融合 ,周边强化 ,血管移位。淋巴瘤多位于颈外侧 ,多不伴血管移位 ,轻度强化。结论 :根据血管的移位及肿瘤的CT强化特点有助于颈部肿瘤的鉴别。
Objective:To discuss CT features and diagnostic value of occupying lesions in the carotid sheath sregion.Methods:21 cases of occupying lesions in the carotid space proved by surgery and pathology were reviewed and analyzed.Results:In 6 cases neurilemmoma, 5 cases showed vessel displacement,with typical “spotted' enhancement. One case neurilemmoma have cystic degeneration without vessel shift and enhancement. Two cases neurofibromatosis demonstrated hypodense, without enhancement and one case with vessel displacement. Carotid body tumor occurred at the divarication of carotid, enhanced intensely and lateral displacement of the vessel. Carotid aneurysm showed a cystoid enlargement with psudocyst and enhanced intensely. Lymphadenopathy always occurred superficial to the vessel and lead to the vessel displacement. Lymphomas had multiple lymphadenopathy in the neck, the lesions enhanced a bit,usually without vessel displacement.Conclusion:CT is helpful in differentiating diagnosis of cervical masses according to local vessel displacement and enhancement features.
