目的:探讨早期强直性脊椎炎的影像学表现特征。方法:回顾性分析2008年1月至2012年12月广东药学院附属门诊部和广东省中医院收治的36例AS患者的影像学资料,观察患者X线片和CT检查的特点。结果:早期病变部位多位于双侧骶髂关节中下部并以髂骨侧为著,主要表现为双侧骶髂关节面不清,边缘模糊、毛糙,虫蚀样骨质破坏、关节面下小囊变,邻近骨质轻度硬化;CT扫描能更清楚显示骶髂关节细微改变,对早期病变(0~Ⅱ级)提高了Ⅰ~Ⅱ个诊断级别。结论:CT扫描对AS病变的早期发现与分期更准确,可提高AS早期诊断率。
Objective: To investigate the imaging features of ankylosing spondylitis in early stage. Methods: The imaging data of 36 patients with AS who were admitted to the affiliated clinic of Guangdong University of Traditional Chinese Medicine from January 2008 to December 2012 were retrospectively analyzed. The characteristics of X-ray and CT examination were observed. Results: The early lesions mostly located in the lower part of the bilateral sacroiliac joint with the iliac side as the main performance of the bilateral sacroiliac joint surface is unclear, the edge of the fuzzy, rough, worm-like bone destruction, joint surface is small Cystic change, adjacent bone mild sclerosis; CT scan can more clearly show the sacroiliac joint subtle changes in early lesions (0 ~ Ⅱ grade) increased Ⅰ ~ Ⅱ diagnostic level. Conclusion: The early detection and staging of AS lesions by CT scan is more accurate, which can improve the early diagnosis rate of AS.
