摘　　要：目的分析卵巢肿瘤蒂扭转的16层螺旋CT表现。方法回顾分析经手术病理证实的12例卵巢肿瘤蒂扭转的CT资料。结果 12例病例中9例扭转侧输卵管增粗。10例扭转肿瘤为囊性或囊实性,7例可见偏心性囊壁增厚,5例行增强扫描者囊壁未见强化。2例扭转实性肿瘤增强扫描没有强化。5例有少量腹水。结论输卵管增粗、附件囊性肿块囊壁增厚、肿块囊壁或实性部分不强化时对诊断卵巢肿瘤蒂扭转有重要意义。16层螺旋CT更易于检出增粗的输卵管。Objective To analyze the CT 16-slices helical features of torsion iof ovarian tumor. Methods CT manifestations of torsion of ovarian tumor in 12 cases proven by surgery and pathology were analyzed retrospectively. Results Of 12 cases, the tube thickening was found on the twisted side in 9. Ten of the ovarian tumors were cystic or cystic-solid, which proved eccentric wall thickening in 7 cases. Five cystic or cystic-solid tumors were lack of enhancement after contrast administration. No enhancement was seen after injecting contrast agent in 2 solid masses. Ascites was present in 5 patients. Deviation of uterus to the side of the twisted ovarian was noted in 7 patients. Conclusion Three findings （tube thickening, smooth wall thickening and lack of contrast enhancement of the internal solid component or the thickened wall） seem to be diagnostic for the twisted ovarian tumor. 16-slices helical CT imaging may be more helpful in detecting a thickened tube.
