Conjoined twins have a rare prevalence and special curiosity among physicians and the general population. The reported frequency varies from 1:50,000 to 1:200,000 pregnancies. Its early diagnosis becomes very important when we think about pregnancy management, method of delivery and neonatal care. We describe two cases of conjoined twins diagnosed by ultrasound and magnetic resonance during prenatal care with the aim to better studying the fetus anatomy. The first conjoined twins were cephalopagus sharing head, thorax and abdominal wall and with two pelvis and four arms and four legs. The second were thoracopagus, united by thorax and part of abdomen. Magnetic resonance imaging contribution was not important to diagnose conjoined twins. However, it was useful to describe the shared organs, contributing to define fetal outcome.
