Ambiguous genitalia: diagnosis, evaluation, and treatment.
The pediatric radiologist plays a significant role in the evaluation and the treatment of infants with ambiguous genitalia. On the first day of life, an investigation should be initiated that includes studies, in particular a sonogram, to demonstrate the presence or absence of a uterus, and a genitogram to define the presence of a vagina. Once gender assignment has been made, information regarding the size of the vagina and its position in regard to the urogenital sinus becomes essential to the pediatric urologist when planning a course for reconstruction. Herein we break down intersex states into four major categories: female pseudohermaphroditism, male pseudohermaphroditism without müllerian structures, and male hermaphroditism with müllerian structures and true hermaphroditism. The role of the radiologist in each of these states is discussed.
