Abstract
INTRODUCTION: We present a case of a 13-week abdominal pregnancy evaluated with ultrasound and magnetic resonance imaging. CASE PRESENTATION: A 34-year-old woman, (gravida 2, para 1) suffering from lower abdominal pain and slight vaginal bleeding was transferred to our hospital. A transabdominal ultrasound and magnetic resonance imaging were performed. The diagnosis of primary abdominal pregnancy was confirmed according to Studdiford's criteria. A laparatomy was carried out. The placenta was attached to the mesentery of sigmoid colon and to the left abdominal sidewall. The placenta was dissected away completely and safely. No postoperative complications were observed. CONCLUSION: Ultrasound examination is the usual diagnostic procedure of choice. In addition magnetic resonance imaging can be useful to show the localization of the placenta preoperatively.
