摘　　要：目的对胸腹部巨大淋巴结增生症的CT和MR的影像学特征进行分析,从而更好开展该病的影像学研究。方法方便选择该院在2017年1月-2018年12月期间收治的40例经手术病理证实为胸腹部巨大淋巴结增生症的患者作为研究对象,回顾性分析这些患者的CT和MR的影像学表现。结果扫描结果显示,肿块为单发孤立的圆形或卵圆形,具有光滑的边缘,而且可以清晰的辨别其与周围结构的边界。局限性肿块均具有超过3.0 cm的直径,其中最大的达到了6.0 cm;多发性肿块则具有1.0~4.0 cm的直径。胸内肿块的分布如下:7例位于右侧肺门,6例位于左侧肺门,4例位于右侧气管旁,4例位于右侧奇静脉隐窝,2例位于左侧主、肺动脉窗,3例多发性。腹内肿块的分布如下:5例位于右侧肾上腺区域,3例位于后腹膜,6例多发性。CT表现如下:病理表现为透明血管型,平扫呈现出等密度的特点,相对比较均匀;MRI表现如下:肿块在SE序列T1WI上表现出等信号的特点,在T2WI表现出高信号的特点。结论胸腹部巨大淋巴结增生症的病理变化情况与其CT和MR的表现具有非常密切的关系,具有非常重要的诊断价值。Objective To analyze the imaging features of CT and MR in massive lymph node hyperplasia of the chest and abdomen,so as to better carry out the imaging study of the disease.Methods A total of 40 patients with massive lymph node hyperplasia confirmed by surgery and pathology from January 2017 to December 2018 were convenient enrolled in our hospital.The CT and MR imaging findings of these patients were retrospectively analyzed.Results The scan showed that the mass was a single round or oval,with smooth edges and clearly distinguishing its boundaries from surrounding structures.The localized masses all have a diameter of more than 3.0 cm,the largest of which was 6.0 cm;the multiple masses had a diameter of 1.0 to 4.0 cm.The distribution of intrathoracic masses was as follows: 7 in the right hilar,6 in the left hilar,4 in the right trachea,4 in the right azygous crypt,and 2 in the left main and pulmonary window 3 cases were multiple.The distribution of intra-abdominal masses was as follows: 5 in the right adrenal gland,3 in the posterior peritoneum,and 6 in multiple.The CT findings were as follows: the pathological manifestations were transparent vascular type,and the plain scan showed the characteristics of equal density,which was relatively uniform;MRI showed the following: the tumor showed the characteristics of equal signals on the SE sequence T1WI,and showed high signal characteristics on T2WI.Conclusion The pathological changes of massive lymph node hyperplasia in the thoracic abdomen have a very close relationship with the performance of CT and MR,and have very important diagnostic value.
