Diabetes in pregnant women could be source of morbidity and mortality if management was not optimal. One of the main complications of diabetes in pregnant women is birth defects. They have an estimated prevalence of 1.5%. They can be isolated or associated to other malformations. Prevention includes systematic screening when monitoring pregnancies, in particular carrying out morphological obstetrical ultrasounds. A case of limb malformation secondary to unbalanced maternal diabetes and absence of prenatal diagnosis despite the high number of ultrasounds that have been performed is reported here. This situation requests more attention to the quality of antenatal ultrasounds caregiving in developing countries.
