摘要
目的探讨早孕期剖宫产术后子宫瘢痕妊娠MRI表现及诊断价值。方法回顾性分析总结10例经临床、病理证实剖宫产术后子宫瘢痕妊娠患者的MRI表现。结果 10例病灶均行手术治疗,9例诊断正确,1例误诊为滋养细胞肿瘤。病灶均位于子宫前下壁,呈圆形或椭圆形,8例病灶可见完整的妊娠囊,2例呈混杂包块状,表现为混杂长T1混杂长T2信号影。6例妊娠囊主要向宫腔内生长,植入子宫壁较浅,与局部子宫肌层分界清晰;4例妊娠囊种植于瘢痕深部,主要向肌层深部生长并向外膨隆,妊娠处子宫壁明显较薄;10例均行DWI,表现为环状或混杂高信号。结论剖宫产子宫瘢痕妊娠的MRI影像表现有一定的特异性,有助于临床分型及术式选择。
To evaluate MRI findings and diagnosis value in the early diagnosis of cesarean scar pregnancy（CSPs）. Methods The MRI manifestations of 10 cases which were diagnosed as CSPs on the basis of surgery and pathology were retrospectively analyzed. Reaults Among 10 patients all had been underwent surgery. 9 cases were definitely diagnosed by MRI and misdiagnosed in 1 cases as trophoblastic disease. All the lesions were located in the anterior inferior wall of uterus, and showed rounded or round-like shapes, 8 cases belonged to Gestational sac type and 2 seemed like mixed masses with long T1 and long T2 heterogeneous signal. 6 cases of gestation sac grew into the uterine cavity mainly, and embedded in the uterine wall superficially and had clear margin with the local uterine muscular layer. 4 cases of gestation sac embedded in the deep area of scar, grew mainly toward the uterine muscular layer and protruded out of the uterine outline, the muscular layer at the lesion became thin. All 10 patients received DWI and showed ring-like or heterogeneous hyperintensity. Concluaion The MRI features of uterine cesarean scar were specific, which was useful to defining its clinical type and selection of operation.
