目的探讨育龄女性u Sp A患者骶髂关节影像学特征。方法对60名育龄女性u Sp A患者行骶髂关节CT检查,测量骶髂关节间隙宽度及骶髂骨皮质厚度,观察骶髂关节间隙清晰程度、骶髂骨皮质边缘光滑程度及皮质下骨质密度情况。结果 53%u Sp A女性病例骶髂关节关节间隙模糊。关节间隙小于2 mm的占65.8%。95%表现为单侧或双侧关节面模糊、骶髂骨面皮质边缘毛糙、软骨下骨质密度不均和软骨下微小囊变等,其中20%关节面分级为3级,u Sp A女性病例骶髂骨皮质厚度随年龄增长逐渐增厚,关节面骨质破坏及皮质增厚以髂骨侧为著。36.6%u Sp A女性病例骶髂关节关节腔内可见线条样点状气体样低密度影。结论育龄女性u Sp A患者骶髂关节间隙模糊、消失、骶髂关节间隙变窄、关节面骨质破坏及分级、关节面下骨质硬化及骶髂关节真空现象的发生率和程度均较正常育龄女性明显增高,骨质破坏在关节髂骨侧更严重。对骶髂关节有异常表现的无症状育龄女性或有临床症状但CT分级为0级或1级的育龄女性,需要根据临床、实验室检查与MR检查进一步确定。
Objective To investigate the imaging features of sacroiliac joint in women of childbearing age with u Sp A. Methods Sixty female patients of childbearing age with u Sp A underwent sacroiliac joint computed tomography (CT) examination. The width of sacroiliac joint and the thickness of sacroiliac cortex were measured. The clarity of sacroiliac joint space, the smoothness of sacroiliac cortex and the cortical bone quality Density conditions. Results 53% u Sp A Female patients sacroiliac joint joint space fuzzy. Joint space less than 2 mm accounted for 65.8%. 95% showed unilateral or bilateral articular surface obstruction, sacrococcygeal cortex edge rough, subchondral bone density and subchondral microencapsulation, etc., of which 20% of the articular surface grade 3, u Sp A female Sacroiliac cortical thickness of patients with age and gradually thickening of the articular surface destruction of bone and cortical thickening of the iliac side. 36.6% u Sp A female patients with sacroiliac joint joint cavity visible punctate gas-like low-density shadow. Conclusions The prevalence and extent of osteopetrosis and sacroiliac joint vacuum in the women of childbearing age are vague and vague in the sacroiliac joint space, narrowing the sacroiliac joint space, and the bone destruction and grading of articular surface, Women of childbearing age were significantly higher bone destruction in the iliac joint more serious. Asymptomatic women of reproductive age who have abnormalities in the sacroiliac joint or in women of childbearing age who have clinical symptoms but have a CT grade of 0 or 1 need to be further identified on the basis of clinical, laboratory, and MR findings.
