Pregnancy is associated with the presence of bone marrow edema (BME) in the sacroiliac joints during the postpartum period. The aim of this study is to evaluate the frequency and localization of sacroiliac joint edema during pregnancy.
This retrospective, monocentric study included pregnant women who underwent pelvic MRI for any reason during their pregnancy. Women with a history of chronic inflammatory rheumatic diseases and minors were excluded. Two experienced readers independently evaluated the presence of bone marrow edema (BME) using a two-plane assessment method: axial and semi-coronal oblique views. Each sacroiliac joint was divided into four quadrants per slice and the presence of deep lesion was also scored.
We included 28 women with a median age of 30.0 [27.0-33.0] years and a median gestational age of 27.5 [25.5-32.0] weeks of amenorrhea. Ten women (36%) presented with at least one BME in a sacroiliac joint, and 3 of these women had bilateral sacroiliac joint BME. BME was observed in 12 of 13 cases (92%) in the lower part of the sacroiliac joint. In 8 cases (66%), the edema was present on both the iliac and sacral sides, in 1 case (8%) only on the iliac side, and in 4 cases (33%) only on the sacral side. There were no correlation between gestational age and the presence of BME.
BME in the sacroiliac joint is common during pregnancy and is typically located in the anterior and inferior parts of the joint, similar to the postpartum period.
产后时期，妊娠与骶髂关节骨髓水肿（BME）的出现有关。本研究的目的是评估妊娠期间骶髂关节水肿的频率和定位。
这项回顾性单中心研究纳入了在孕期因任何原因接受盆腔MRI检查的孕妇。排除有慢性炎症性风湿性疾病史的女性和未成年人。两名经验丰富的阅片者采用双平面评估方法（轴位和半冠状斜位）独立评估骨髓水肿（BME）的存在情况。每一层面将每个骶髂关节分为四个象限，并对深部病变的存在情况进行评分。
我们纳入了28名女性，中位年龄为30.0[27.0 - 33.0]岁，中位孕周为闭经27.5[25.5 - 32.0]周。10名女性（36%）在骶髂关节出现至少一处BME，其中3名女性双侧骶髂关节均有BME。13例中有12例（92%）在骶髂关节下部观察到BME。8例（66%）水肿同时出现在髂骨侧和骶骨侧，1例（8%）仅出现在髂骨侧，4例（33%）仅出现在骶骨侧。孕周与BME的存在之间无相关性。
妊娠期间骶髂关节的BME很常见，且通常位于关节的前部和下部，与产后时期相似。
