Interstitial pregnancy is a rare and dangerous form of
ectopic pregnancy that can be mistaken for a normal intrauterine
pregnancy on
ultrasonography leading to catastrophic results.
Gynecologist should be aware of the potential for mistaking an
interstitial pregnancy for intrauterine
pregnancy. We present a case of 14 weeks
interstitial pregnancy misdiagnosed on abdominal
ultrasonography as intrauterine
pregnancy with
ascites. She was treated as sub-acute
intestinal obstruction with severe
anemia in
pregnancy for 2 days. The correct
diagnosis was first made at
emergency laparotomy which showed
hemoperitoneum and rent involving the right superolateral end of the
uterus, with
fetus and
placenta lying in pouch of Douglas. Wedge resection of the right superolateral end of
uterus along with repair done. Lack of suspicion and lack of expertise are a common cause for missing this rare
ectopic pregnancy.
