RESUMO
UNLABELLED: The intra-abdominal umbilical vein varix is very uncommon, characterized by a dilation of the vein, usually located between its entry into the abdomen and completion in the portal system. However, the location of this anomaly to extra-abdominal level is very unusual and more difficult to diagnose by ultrasound. CLINICAL CASE: We present a case undiagnosed during pregnancy, demonstrating cord abnormality in its extra-abdominal portion and confirmed later by the pathology study. It was a gestation of 36 + 6 weeks, ending by performing emergency caesarean section for abnormal fetal heart rate, with good perinatal outcome. The diagnosis was made after placental delivery, by the existence of fibrotic cystic structure in the middle third of the umbilical cord.
