【摘要】：目的:探讨干燥综合征(SS)的腮腺CT表现特点。方法:收集我院确诊的SS患者13例行腮腺CT扫描,选取14例无腮腺疾病及口干症状行颈部CT扫描者作为对照组。观察腮腺的密度是否均匀、脂肪密度的有无、腺体实质的密度、钙化的有无。用独立样本t检验比较病例组与对照组腮腺实质的CT值有无统计学差异。结果:对照组腮腺呈均匀低密度。病例组双侧腮腺密度不均,可见弥漫性脂肪组织浸润,呈点片状、网格状、斑片状甚至几乎完全取代腮腺实质;腮腺实质密度增高。5例10个腮腺内见弥漫性分布的多发点状钙化。病例组和对照组腮腺实质的平均CT值分别为(-3.42±24.11)HU和(-25.43±20.32)HU,病例组高于对照组,差异有统计学意义(t=3.574,P=0.001)。结论:SS患者腮腺密度不均,出现弥漫性脂肪组织浸润和腮腺实质密度增高为特征性的CT表现,并可出现特征性的弥漫性点状钙化。CT可以作为SS的一种筛查手段。
[Abstract]:Objective: to investigate the CT features of parotid gland in Sjogren's syndrome (SS). Methods: thirteen patients with SS underwent CT scan of parotid gland and 14 patients without parotid diseases and dry mouth symptoms were selected as control group. The density of parotid gland, the density of fat, the density of glandular parenchyma and calcification were observed. The CT value of parotid parenchyma was compared with that of control group by independent t test. Results: the parotid gland of the control group was homogeneous and low density. In the case group, the density of bilateral parotid gland was uneven, and diffuse fat tissue infiltration was seen, which was spot flake, gridding, and patchy or almost completely replaced parotid gland parenchyma. The density of parotid parenchyma was increased in 10 parotid glands. The average CT values of parotid parenchyma in the case group and the control group were -3.42 卤24.11)HU and 25.43 卤20.32HUU, respectively, which were higher in the case group than in the control group, and the difference was statistically significant (P < 0.05). Conclusion the density of parotid gland is uneven, diffuse adipose tissue infiltration and parotid parenchyma density increase are characteristic CT findings, and characteristic diffuse punctate calcification. Ct can be used as a screening method for SS.
