Furthermore, 16 cases of UTP were missed by ultrasonography. A total of 130 patients had a mass detected by ultrasonography, among whom the mass and ipsilateral ovary were distinguishable in 102. The embryo sac type was found in 40.00% (52\/130), while the heterogeneous mass type was found in 60.00% (78\/130) of patients. The maximum length and diameter of the ectopic pregnancy mass ranged from 10 to 68\u2009mm (mean size, 26.42\u2009\u00b1\u200911.39\u2009mm). No blood flow was observed in or around the mass in 67.69% (88\/130) of patients. Lateral tubal thickening of the mass was found in 47.69% (62\/130) of patients. Endometrial thickness was \u226410\u2009mm in 67.80% (99\/146) of patients. The intima was mostly hyperechoic in 72.60% (106\/146) of patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A paraovarian mass, thickened fallopian tube, uterine endometrium with a thickness of \u226410\u2009mm, and high echo are important indicators of early UTP.
