Patterns of injury to the levator ani in parous women with laparoscopy-negative, chronic pelvic pain (CPP) are described. A consecutive series of 26 parous women with laparoscopy-negative CPP, had magnetic resonance imaging (MRI) in axial, coronal and sagittal planes. Similar imaging studies were performed in 32 parous women having MRI scans for other clinical indications and 20 asymptomatic, nulliparous women. Three patterns of injury/defect to the levator ani (LAd) were observed in 20/26 patients with unexplained pelvic pain: avulsion of the pubococcygeus from its origin at the pubis (LAd I, 3/20), avulsion of the pubococcygeus from its origin at the arcus tendineus levator ani (LAd II, 14/20), and, loss of shape and form of the pubococcygeus (LAd III, 6/20). Three patterns of injury to the levator ani have been described with MR imaging in parous women with unexplained CPP.
描述了腹腔镜检查结果为阴性的经产妇慢性盆腔疼痛（CPP）患者肛提肌的损伤模式。连续纳入26例腹腔镜检查结果为阴性的经产妇CPP患者，进行了轴向、冠状面和矢状面的磁共振成像（MRI）检查。另外32例因其他临床指征进行MRI扫描的经产妇以及20例无症状未生育女性也进行了类似的成像研究。在20/26例不明原因盆腔疼痛患者中观察到三种肛提肌损伤/缺陷模式：耻骨尾骨肌从耻骨起始处撕脱（LAd I，3/20），耻骨尾骨肌从肛提肌腱弓起始处撕脱（LAd II，14/20），以及耻骨尾骨肌形态和结构丧失（LAd III，6/20）。通过MR成像已经描述了经产妇不明原因CPP患者肛提肌的三种损伤模式。
