目的 讨论糖尿病合并肺结核的CT表现特点。方法 本文 2 8例全部作了常规胸部CT扫描以及局部病灶区加扫 1mm薄层 ,9例作了动态增强扫描 ,延迟时间分别在注射造影剂 80～ 10 0mL后的 30s ,2min和 5min。结果 本组 2 8例共有 5 1个肺段发现病变 ,其中肺结核常见部位占 70 6 % ,少见部位 2 9 4% ,17例 (6 0 7% )呈多个肺段病变 ,11例 (39 3% )表现为单个肺叶或肺段病变 ,其中 8例发生在少见部位。CT征象多表现为活动性病变 ,其中大片状实变影 (17 4% )、空洞影包括 1例多发小空洞 (13 1% )、磨玻璃征 (10 9% )和树芽状支气管播散病灶(17 4% ) ,但结节和肿块影 (30 4% )也不少见 ,并且其中 7例病灶呈边缘强化。本组CT正确诊断 2 3例 (82 1% ) ,误诊 5例 (17 9% )。结论 在少见部位的较高发病率和实变区内多发小空洞是糖尿病并发肺结核较为特征性的CT表现 ,具有一定的诊断价值。
Objective To discuss the CT features of diabetic patients with pulmonary tuberculosis. Methods Twenty-eight patients underwent conventional chest CT scan and local lesion area scan with 1mm thin layer. Nine patients underwent dynamic contrast-enhanced scanning. The delay time was 30s, 2min and 5min after injection of contrast agent 80 ~ 100mL respectively. Results A total of 51 lung segments were found in 28 cases of this group. Among them, 70.6% of common tuberculosis cases, 294% of uncommon cases and 17 pulmonary lesions (60.7%) were found in 11 cases (39 cases) 3%) showed a single lung or lung lesions, of which 8 occurred in rare sites. Most of the CT findings were active lesions, including massive lysis (17 4%), empty shadow including 1 case of multiple small empty holes (13 1%), ground glass sign (109%) and sprouting bronchial stenosis (17 4%), nodules and mass (30 4%) were not uncommon, and seven of them showed edge enhancement. This group of CT correct diagnosis of 23 cases (82 1%), misdiagnosed 5 cases (17 9%). Conclusions The higher incidence of rare sites and multiple small cavities in the consolidation area are more typical CT findings of diabetes complicated with pulmonary tuberculosis and have certain diagnostic value.
