Imaging Analysis of Enlargement of Cervical Lymph Node / 实用放射学杂志

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.
