Case report 1

Luis Diaz Guerrero, MD

This is a 28-year-old pregnant woman, G2P1, referred to our unit with the suspect of meconial peritonitis at 34 weeks. The ultrasound examination revealed a male fetus with normal growth (2500g). In the abdomen, a complex solid ovoid with bone mineralization mass was seen. Long bones, ribs and spine with a feeding vessel from the fetal aorta were identified. The mass measured were 6 x 4,5 x 5 cm.

Fetal Doppler was normal. The baby was born at 37 weeks and underwent to surgery due to an acute intestinal obstruction. The fetus-in-fetu was removed with a good evolution of the host fetus.
