Methods A retrospective analysis of 2 cases of cornual pregnancy clinically after treatment, the dynamic changes in the performance of sonography, gross and histological morphology, and literature review. Results The results of uterine horn pregnancy showed that the uterine horn showed unequal echogenic mass at the implantation site and abundant blood flow signals with low resistance arterial spectrum.

Conclusions After interventional treatment of uterine hormones or discontinuation of fetal operation, sonographic findings resemble trophoblastic tumors and should be identified by clinical and serum β-hCG tests. After intervention, gestational sac excretion may have a waiting period of several months.
