    Abstract: Heterotopic pregnancy is defined as coexistence of intrauterine and ectopic pregnancy at the same
time. It although common with assisted reproductive techniques is very rare in natural conception. Ruptured
ectopic pregnancy carries a significant maternal mortality and morbidity, so timely diagnosis and management
is crucial. We report a case of heterotopic pregnancy in a 26 year old woman presented with acute abdomen.
Immediate surgical intervention was done with diagnosis of ruptured ectopic pregnancy. This case suggests
that intrauterine gestational sac may be a false reassurance, especially in women presenting a pelvic pain.
Heterotopic pregnancy can occur in the absence of any predisposing risk factors. Early diagnosis is necessary
for the best maternal and intrauterine fetus outcome, hence every physician should be aware of the possibility
of heterotopic pregnancy.
