摘要
提高对颈淋巴结结核的认识和CT诊断的正确性。材料和方法：经CT检查的颈淋巴结结核33例，与同期颈肿块（除颈器官肿瘤外）49例作CT对照研究，均经病理及临床证实。结果：（1）结核发病中位年龄29．2岁，明显年轻于恶性肿瘤组（556岁）。（2）结核淋巴结坏死率和包膜高度强化率均高达81．82％，结内坏死面积（≥1／2）者达7576％。（3）本文依颈淋巴结结核的CT形态分布提出分型：单纯型（Ⅰ－Ⅳ）、混合型：单纯型又可分为Ⅰ型（单个淋巴结，直径＜20mm）、Ⅱ型（串珠型）、Ⅲ型（多房型）、Ⅳ型（融合呈大单房或单个直径≥20mm）。其中Ⅱ型具诊断特异性。结论：CT对颈淋巴结结核有诊断价值。
For promoting the recognization of cervical lymph node tuberculosis and the CT diagnostic accuracy. Materials and Methods: 33 oasses of cervical lymph node tuberculosis with their CT images were analysed, together with 49 cases of cervical masses(except the cervical organic tumors), in the same tage were made for comparison study, which all were proven clinically and pathologically. Resaults: (1)The mean age of tuberculous incidence is 29. 2, which is younger the the malignant tumor group(55. 6years old) (2) the necrotic rate and enhanced node capsule rate of cervical lymph node tuberculosis reached same hight(81. 82%). The rate of lymph node in which the necrotic area larger than 50% is up to 75. 76% in CT scans (3) According to the CT findings of cervical lymph node tuberculosis, it may be divided into simple and mixed types. Simple type Ⅰ, (single lymph node, diameter<20mm), type Ⅱ(toruliform), take Ⅲ(multi-locular) and type Ⅳ (large single node or large confluent node, diameter≥20mm). Type Ⅱ has the special nature for diagnosis. Conclusion: CT has important value for the diagonsis of cervical lymph node tuberculosis.
