The TRAP sequence involves a pump twin perfusing a recipient twin through vascular anastomosis. Here, we report two cases with different presentations of acardiac twin."n"nCase report: The first acardiac twin was composed of a healthy fetus and a fetus with proximal of trunk, pelvic and lower limbs without head, neck and arms (acardia acephalus- classic form). The pregnancy was followed with ultrasonography and pregnancy terminated at 29 weeks, because there was abnormal doppler of ductus venosus and non-reassuring NST in pump twin. The second acardiac twin first time was diagnosed at a rotine ultrasonography at 26 weeks gestation as a healthy fetus and an acardia fetus with a hypoplastic lower limb and intestine like organ (amorphic mass). The pregnancy following, normal infant was born with a sac with some loops of the intestine at term. Each two cases were diagnosed at 26 week and each was delivered healthy pump twin."n"nConclusion: Acardiac twin has different presentation and here we presented two end of acardia twin presentation with different management and outcome.
