摘要
目的观察儿童卵巢扭转的MSCT表现。方法回顾性分析23例经手术或病理检查证实的儿童卵巢扭转MSCT资料,主要观察扭转后卵巢大小和形态、蒂扭转、子宫及附件周围血管异常改变。23例中,6例仅接受CT平扫,17例接受CT平扫及双期增强扫描。结果 23例患儿中,原发性卵巢扭转4例,继发性卵巢扭转19例;发生于左侧9例,右侧14例。23例中,MSCT示15例卵巢体积增大且密度增高,12例增大的卵巢表面可见数量不等的增大滤泡。23例中,11例(11/23,47.83%)可见卵巢蒂扭转。CT增强扫描动脉期及门静脉期均见卵巢扭转侧子宫及附件周围血管增多、增粗、走行异常。15例子宫不同程度变形、移位;11例可见盆腔内少量积液。结论儿童卵巢扭转的MSCT表现具有一定特征性,MSCT检查有助于提高卵巢扭转的检出率。
Objective To observe the MSCT findings of ovarian torsion in children. Methods The MSCT findings of 23 chil- dren with ovarian torsion confirmed by surgery or pathology were retrospectively analyzed. The size and shape of ovaries, twisted pedicles and vascular changes nearby the ovarian torsion were studied. MSCT plain scan was performed on 23 cases, as well as dual-phase enhanced scan was performed on 17 cases. Results Totally there were 4 cases of primary ovarian torsion and 19 cases of secondary torsion. The torsion occurred on the left ovary in 9 cases and occurred on the right ovary in 14 cases. The enlarged and hyperdense ovaries on MSCT images were found in 15 of 23 cases. And the surfaces of ovaries surrounded by plump follicles were found in 12 cases. Eleven cases were detected with twisted pedicle sign. Both of the artery-phase and portal vein-phase enhanced CT images showed the vessels nearby ovarian torsion increased, thickened and distorted. The uterine distortion and displacement were found in 15 cases and mild pelvic effusion was found in 11 cases. Conclusion MSCT findings of pediatric ovarian torsion is characteristic, which is helpful to improve the detection rate.
