A case of an unruptured intrafollicular ovarian pregnancy of 8 gestational weeks diagnosed by ultrasonography in a virtually asymptomatic patient is reported. A 32 year-old woman with 1 vaginal delivery 8 years ago presented with a history of intermittent spotting after removal of an IUD during her last menstrual period 4 weeks ago. IUD was inserted 6 years prior. The patient was symptom-free and showed no abnormal findings upon vaginal examination. Transvaginal ultrasonography however disclosed a gestational sac with a live embryo within the left ovary. The woman was operated on via laparotomy without delay. The intraoperative finding showed a normally appearing corpus luteum in the intact left ovary without any visible abnormality of the pelvic organs. Having in mind the US finding a resection of the corpus luteum was done revealing the gestational sac within it. The authors describe the following three US signs specific of unruptured intrafollicular ovarian pregnancy: extremely thickened uniformly echogenic wall of the sac, the sac is partially surrounded by ovarian structure, no corpus luteum is detected in either ovary. The essential role of transvaginal ultrasonography in the precise diagnosis of the ectopic pregnancy and its location is emphasized. The absence of specific complaints and findings until rupture of the ovary occurs and the association of ovarian pregnancy and IUD are also confirmed by the case-report.
