Overview

There are no CT scan findings associated with amenorrhea. However, a CT scan may be helpful in the diagnosis of the diseases that can cause amenorrhea, such as Turner syndrome, androgen insensitivity syndrome and also anatomic genital defects.

Turner syndrome

  • The main finding on a CT angiogram suggestive of Turner syndrome is Coarctation of aorta.[4]
  • The CT angiogram shows the presence of decreased caliber of the aorta in the isthmus at the arrival of the remaining segment of the ductus arteriosus.
  • Opacification of the ductus arteriosus is observed in its entire length from its origin from the aorta.
















Androgen insensitivity syndrome






















Anatomic genital defects

  • Findings on a CT scan suggestive of septate uterus include:[6]
    • Convex fundal contour
    • Acute angle of < 75% between uterine cavities
