SIMA Bin,QIU Xiaowei. The clinical significance of MR in the diagnosis of cesarean scar pregnancy[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2014, 44(12): 905-908.
Abstract：Objective: To analyze MR findings of cesarean scar pregnancy (CSP). Methods: The MR findings in 11 patients who were diagnosed as CSP by surgery and pathology from January 2013 to September 2013 were retrospectively analyzed, and the features of the MR findings were summarized. Results: All gestational sacs (11) were clearly detected by MR. Among the 11 cases, gestational sac presented as cystic mass with smooth margin located within the scar of uterine wall at the lower anterior uterus in 4 cases. In 1 of the 4 cases, gestational sac was found within the myometrium, whereas in the remaining 3 cases, gestational sac was found partially within the myometrium with extension into the uterine cavity. In the remaining 7 of the 11 cases, gestational sac presented as irregular, multilobolated mass, growing deeply into the myometrium as well as into the uterine cavity. In 1 of the 7 cases, gestational sac was found growing outside the uterine cavity, the signal of the uterine wall was disconnected, and the bladder was pressured. In the 7 cases, gestational sacs were rich in blood supply. An enhancing solid component with a heterogeneous mass could be seen. 7 cases showed mass enhancement in the surgical scars or around the scars, and no enhancement in the part of hemorrhage and liquid. The Cesarean scar was clearly detected by MR. Conclusion: The test of MR is safe and effective, which can provide useful information in the diagnosis of CSP.
