title: First trimester diagnosis of sirenomelia by 2D and 3D ultrasound.
abstract: A case of sirenomelia in a 27-year-old woman detected at 11 weeks 5 days of gestation is presented. It was suspected by two-dimensional sonography and color Doppler imaging. Three-dimensional ultrasound confirmed the final diagnosis. With detailed evaluation of the acquired volumes, valuable information was obtained about the anatomical as well as pathological features of the fetus.
