摘要
目的探讨颈部常见淋巴结病变的MDCT影像表现特点与其病理的相关性。方法收集经病理证实的颈部淋巴结病变62例,包括淋巴瘤28例,转移瘤21例,淋巴结结核13例。在MDCT图像上,观察病变的位置、形态、大小、密度及其与周围结构的关系。结果淋巴瘤均为软组织密度结节或肿块;27例边界清楚,仅1例包膜外侵犯;24例密度均匀,均匀轻度强化或不强化;4例部分融合,其中2例内部发生液化坏死、边缘轻度不规则强化。淋巴结转移瘤以软组织密度结节为主要表现;13例形态规则、边界清楚;8例融合成块,形态不规则,其中5例包膜外侵犯;15例密度不均匀,不规则强化,其中11例合并中心坏死区;6例密度较均,其中2例显著不均匀强化、3例轻微强化、1例无强化。淋巴结结核主要表现为不均匀密度结节或肿块;10例形态规则,边界清楚;3例有融合,边界不清;9例密度不均匀(其中3例有钙化),内部明显坏死,边缘环状或多房状强化;4例密度均匀,明显或轻度均匀强化。结论 CT可揭示颈部淋巴结病变的病理基础,并存在一定的影像学表现特点。
Objective To determine relationship between MDCT features and pathology in cervical common lymphnode diseases.Methods A retrospective collection of pathologically confirmed cervical lymph node disease in 62 cases,including 28 cases of lymphoma,21 cases of metastatic tumors,13 cases of lymph node tuberculosis.Imaging observation was focused on the Lesions,location,shape,size,density and their relationship with surrounding structures.Results Lymphoma are all of the soft tissue density nodule or mass;27 cases of clear boundary,only 1＇sinvasion is beyond capsule;24 cases of iso-density,evenly slight enhanced or no enhancement;4 cases are partially merged,of which the two are liquefaction necrosis in it with their edge slightly irregular enhanced.Metastatic lymphoma are mainly soft tissue density nodules;13 cases have a regular shapes and a clear boundary;8 cases are merge into blocks,have a irregular shapes,ofwhich 5＇s invasion are beyond capsule;15 cases of uneven density,irregular enhancement,including 11 cases with central necrotic area;6 cases are almost iso-density,2 are significantly uneven enhancement,3 are slightly enhanced,1 is no enhancement.Tuberculous lymph nodes are mainly uneven density nodule or mass;10 cases have a regular shapes and a clear boundary;3 cases are merged and have a ill-defined edge;9 cases have a uneven density（of which 3 cases have calcification in it）,and significant necrosis within it,Edges are ring-like or multi-room-like enhancement;4 cases of iso-density,obviously or slightly even enhancement.Conclusion The MDCT features correlate with the pathology characteristics in cervical lymphnode diseases.
