Intramural Ectopic Pregnancy Misdiagnosed as Choriocarcinoma: A Case Report
Authors:  Weina Guo, M.M., Min Li, M.M., and Yi Shen, M.D.
BACKGROUND: Intramural pregnancy, accounting for <1% of ectopic pregnancies, is a rare but potentially life-threatening condition due to the potential for uterine rupture. In most cases, the diagnosis of intramural pregnancy is not made until uterine rupture or surgery.

CASE: A 29-year-old primi-gravid woman was referred for a suspicion of choriocarcinoma with persistent elevated serum β-hCG. She had previously undergone a dilation and curettage procedure and discontinuous methotrexate therapy at the local hospital. The diagnosis of intramural pregnancy was confirmed, and the lesion was removed surgically.

CONCLUSION: The preoperative diagnosis of intramural pregnancy is difficult, but current diagnostic tools can provide important clues. Increasing the awareness of this disease is of great importance.
