Introduction: Embryology is the biological science that studies the prenatal development of organisms. Interest is to clarify the gross anatomy and explain how they develop normal and abnormal structures, such as congenital malformations. Purpose: This paper describes the macroscopic and radiographic morphology found in malformed fetuses. Materials and methods in the laboratory of experimental embryology malformed fetuses were studied footage being photographed with Kodak film radiographic D speed, size 3x4 cm Kodak D-speed film, size 6x8 cm. The radiation generating device used was 70 kV and 8 mA, with an exposure time of 0.25 seconds at an object-focus distance of 40cm, fixed anode tube. The radiogenic fluids used to process Kodak film by the method visual. Results: Based on macroscopic observation were identified in a fetal omphalocele, acraneo, rachischisis almost complete bony bump on the neck, absence of parietal, occipital and lumbar vertebral arches. Eyes retracted. Was found radiographically normal process of calcification of upper and lower limbs. Vertebrae, ribs and skull with delayed calcification, with the abnormal-looking skull. In another macroscopic observation revealed fetal anencephaly and spina bifida, rachischisis. Radiographically, no signs of calcification. Conclusions: Macroscopic identification allowed to classify the type of malformations and radiographic imaging features of ossification found altered in fetuses. Knowledge about normal development and causes of congenital malformations is necessary to incorporate preventive measures that allow the embryo and fetus to achieve normal development.
