The incidence is one in 35.000 births and one in 100 monozygotic twin pregnancies. It is characterized with a recipient fetus exhibiting lethal anomalies including acardia and a pump fetus. Mortality is usually due to heart failure or premature labor caused by polyhydramnios of pump fetus. Herein, we report a case of TRAP sequence that emphasizes the importance of gray-scale and color Doppler imaging in the diagnosis and management of TRAP sequence.eninfo:eu-repo/semantics/openAccessUltrasoundPregnancyTwinArticle123WOS:0003608086000132-s2.0-849342886442655726810.5812/iranjradiol.12(3)2015.14979Q4Q4
