Abdominal pain is a common complaint during pregnancy and nonobstetric causes can require an urgent surgical approach.Normal pregnancy factors, such as dislocation of abdominal and pelvic structures by the uterus may delay a precise diagnosis, which can be harmful to both mother and fetus.The most frequent conditions are acute appendicitis, biliary disease, intestinal obstruction, pancreatitis, upper tract infection and abdominal trauma.Less common causes but also important include urinary lithiasis, ovarian torsion, epiploic appendagitis. US can be inconclusive in the evaluation of the pregnant woman.MR is a non-invasive and non-ionizing imaging modality, with excellent tissue contrast and no evidence of deleterious effects to the fetus.
