What is it about?
Monochorionic twin pregnancies are characterized by the presence of vascular connections between the twins. These can be the cause of pathologies such as transfuser-transfused syndrome or TRAP syndrome, defined as the association of an acephalic acardiac twin and a healthy twin.

Why is it important?
This syndrome is very rare and is associated with a high mortality rate in the healthy twin due to anemia and heart failure. Prenatal diagnosis is possible, enabling appropriate monitoring and therapeutic measures to be taken to interrupt the vascular anastomoses between the twins, thereby achieving selective fœticide.
Perspectives
The acephalic acardiac twin, a particular form of transfuser-transfused syndrome. Also known as twin reversed arterial perfusion (TRAP) syndrome. It is a rare malformation, accounting for less than 1 in 35,000 births, and is seen exclusively in monochorionic twin pregnancies, affecting less than 1% of them [1]. We report a case of an acephalic acardiac fetus diagnosed on ultrasound at 18 weeks' amenorrhea (SA). Early antenatal diagnosis is essential, enabling appropriate follow-up and even treatment [2-4].
