Abstract

We retrospectively analyzed the features of the size, morphology, attenuation, the enhancement patterns, and anatomic distribution of 45 patients with mediastinal tuberculous lymphadenitis shown on contrast-enhanced multislice spiral CT (MSCT). 80% of the patients showed peripheral enhancement, and 38% of them showed multilocular appearance. deltaCT (The CT on enhanced scan minus that on the unenhanced scan) in the central area (15 +/- 12) HU was less than that in the peripheral area (27 +/- 16) HU (P < 0.01). The enlarged lymph nodes were predominantly distributed in the regions of 4R (87%), 2R (76%), 7 (73%), 10R (62%), and 4L (51%). MSCT could reveal the enhancement patterns and predominant anatomic distribution, which was of great value for the diagnosis of mediastinal tuberculous lymphadenitis.

摘要

我们回顾性分析了45例经多层螺旋CT（MSCT）增强扫描显示的纵隔结核性淋巴结炎患者的大小、形态、密度、强化方式及解剖分布特点。80%的患者表现为周边强化，其中38%表现为多房样。中心区域的deltaCT（增强扫描CT值减去平扫CT值）为（15±12）HU，低于周边区域的（27±16）HU（P<0.01）。肿大淋巴结主要分布于4R区（87%）、2R区（76%）、7区（73%）、10R区（62%）和4L区（51%）。MSCT能够显示强化方式及主要解剖分布，对纵隔结核性淋巴结炎的诊断具有重要价值。
