RESUMEN
Intramural pregnancy is among the rarest forms of ectopic pregnancy. Since it has been first reported by Doederlein in 1913, 37 cases were reported in worldwide literatures. The pathologic criteria required for intramural pregnancy is that the product of conception is completely surrounded by uterine musculature and is separated from the uterine cavity and the fallopian tube or round ligament. Because of the difficult early diagnosis of intramural pregnancy, most cases were found after the onset of complications such as uterine rupture, shock and hemoperitoneum. Early detection of intramural pregnancy with the use of transvaginal ultrasonogram is important, and MRI is a useful, noninvasive imaging modality. We report a case of successful conservative chemotherapy for a intramural pregnancy with brief review of literatures.
