RESUMEN
OBJECTIVE: To provide an overview of the etiology and early dia-gnosis of triple pregnancy, with emphasis on the possibilities of ultrasound and magnetic resonance (MR) imaging. METHODOLOGY: Processing of data from the available literature on the issue of triple pregnancy. CONCLUSION: Spontaneous triple pregnancy conception is rare. In most cases, it is a concept associated with assisted reproduction methods. Multiple pregnancy is associated with a higher incidence of complications during pregnancy and childbirth, but it also has its own specific complications. Chorionicity and amnionicity of multiple pregnancies are two important parameters in determining the strategy of dispensary care in pregnancy and management of childbirth. The use of ultrasound and MR imaging is crucial for their accurate determination in early pregnancy.
