Evaluate jugulodigastric node size in cancer-free patients.
Retrospective review of 234 neck CT angiograms was performed. Known neoplasm, inflammation or poor imaging were excluded. Maximal diameter of the largest jugulodigastric node in the axial plane bilaterally was measured.
172 patients (median age=62) were included. Jugulodigastric node size decreased with age and was statistically significant between those above and below 62years. Patients 20-30years had mean 14.4mm (7.5-20.1mm).
Although 15mm is considered the normal maximum long-axis size of the jugulodigastric node in cancer patients, average size in younger cancer-free patients is commonly above 15mm.
评估无癌患者的颈静脉二腹肌淋巴结大小。
对234例颈部CT血管造影进行回顾性分析。排除已知的肿瘤、炎症或成像不佳的情况。测量双侧轴平面上最大颈静脉二腹肌淋巴结的最大直径。
纳入172例患者（中位年龄=62岁）。颈静脉二腹肌淋巴结大小随年龄增长而减小，62岁以上和以下患者之间差异有统计学意义。20 - 30岁患者的平均直径为14.4mm（7.5 - 20.1mm）。
尽管在癌症患者中，15mm被认为是颈静脉二腹肌淋巴结正常的最大长轴尺寸，但年轻无癌患者的平均尺寸通常超过15mm。
