Splenic injury during pregnancy after blunt abdominal trauma is rare. The physiological and anatomical changes during pregnancy modify the clinical, biological and radiological signs. The authors report a case of a 30-year-old-woman in the 32nd week of pregnancy, with an isolate splenic injury after a motor vehicle accident. Splenectomy was realised 4 days after an initial decision of abstaining from surgery. In pregnancy, the frequency of recurrent bleeding, the possibility of concomitant uterine injuries and the risk of foetal loss should modify the surgeon's attitude to splenic rupture after abdominal blunt trauma.
