【摘要】 目的探讨颈部肿大淋巴结影像表现特点,提高诊断的准确性。方法66例经临床和病理证实的颈部肿大淋巴结患者,均进行CT和/或MR I检查,对比分析他们的影像学表现。结果多发的转移性淋巴结与多发的结核性淋巴结在位置分布上有显著性差异(P=0.006)。转移性淋巴结环形强化20例,其薄壁环形强化19例,占95%,而淋巴结结核环形强化5例均为厚壁环形强化,两者具有显著差异性(P=0.000)。转移性淋巴结中心坏死占78%,而淋巴瘤仅占36%,两者有显著性差异(P=0.018)。结论根据颈部肿大淋巴结位置分布和影像表现特点,大部分可做出正确诊断。更多还原

【Abstract】 Objective To study the imaging features of cervical lymphnode enlargement so as to improve the diagnosis of cervical lymph node disease.Methods CT and MRI appearances of 66 patients with pathologically-proved cervical lymph nodes disease were comparatively analyzed.Results There were significant difference in distribution of the multiple metastatic lymph node and lymph node tuberculosis(P=0.006).The ring-shaped enhancement were found in 20 cases with metastatic lymph nodes,19 of which were shown as thin-wall enhancement,its rate was 95%, and 5 ring-shaped enhancement of lymph node tuberculosis were shown as thick-wall enhancement.The former of which was significant difference than that of the latter(P=0.000).Of all central necrosis,it was significant difference between the metastatic lymph nodes(78%) and lymphoma(36%)(P=0.018).Conclusion According to the imaging features of cervical lymph nodes enlargement,their location and distribution,all of them may be diagnosed correctly.更多还原
