Ultrasonography is unnecessary for girls with a definite diagnosis of CPP. If performed, however, ultrasonography usually reveals bilaterally enlarged ovaries, often with multiple small follicular cysts, and an enlarged uterus with an endometrial stripe.

Pelvic ultrasonography is essential when precocious pseudopuberty is suspected in girls (based on examination or hormone levels), because an ovarian tumor or cyst may be detected.
