摘要
目的探讨5例腹腔淋巴结干酪样坏死的MSCT表现并结合文献分析,旨在加深对于腹腔淋巴结结核(LNT)的认识并降低影像误诊率。方法回顾性分析经手术病理证实的5例LNT患者的CT表现及临床资料,观察病变的部位、大小、形态、边界、增强前后CT值并病理对照;男3例,女2例,年龄2~56岁,平均(32.6±21.3)岁。结果 2例位于髂血管旁,1例位于胰周,1例位于肠系膜根部,1例位于腹膜后,病变大小3.1~6.7 cm,平均(4.5±1.57)cm;5例均表现为分叶状囊实性团块,边界不清并包绕邻近组织结构,病灶引流区可见肿大淋巴结,增强扫描后特征性表现为"蜂房状"强化或不均匀性环形强化。结论腹腔淋巴结干酪样坏死具有一定的MSCT特征,"蜂房状"强化的形态学特征对于诊断具有重要意义。
Objective To analyze the MSCT manifestations of caseous necrosis of 5 lymph nodes in the abdominal cavity and combine literature analysis, in order to deepen the understanding of abdominal lymph node tuberculosis and reduce the rate of misdiagnosis of images. Methods The CT findings and clinical data of 5 patients with lymph tuberculosis confirmed by surgical pathology were retrospectively analyzed.The lesion location, size, morphology, border, CT value before and after enhancement, and pathological control were observed;3 of them were male and 2 were female.The age ranged from 2 to 56 years, with an average age of(32.6 ± 21.3) years. Results 2 cases were located near the iliac vessels(2/5),1 case was at the small omentum(1/5),1 case was at the mesenteric(1/5),1 case was at the retroperitoneum(1/5),the size of the lesion was 3.1~6.7 cm, with an average of(4.5 ± 1.57) cm;5 cases showed lobular cystic solid masses with unclear borders and surrounding tissue structures and enlarged lymph nodes were seen in the drainage area of the lesion. After the enhancement, itwas characterized by "honeycomb-like" obvious enhancement or heterogeneous ring enhancement. Conclusion Caseous necrosis of abdominal lymph nodes has certain MSCT characteristics, and the morphological characteristics of "honeycomb-like" enhancement are of great significance for diagnosis.
