Usefulness of abdominal ultrasonography with studies of the intestinal loops in Turner syndrome patients

Turner syndrome, a chromosomal disorder caused by partial or complete absence of one of the two X chromosomes, is characterized by an increased incidence (compared with that in the normal population) of either autoimmune disorders, including chronic inflammatory bowel diseases, or angiodysplasia of the small intestine. Because ultrasonography and color Doppler ultrasound are widely used to investigate gastrointestinal disorders, we decided to carry out an ultrasound-based screening study in patients with Turner syndrome to determine whether this method might be useful in the follow-up of this population.
