Ultrasonographic and clinical parameters for early differentiation between precocious puberty and premature thelarche

Abstract

Increased uterine and ovarian measurements may be an early and sensitive sign of PP. Pelvic ultrasound, a noninvasive, inexpensive, and reliable tool, may give the clinician a complementary indication to the GnRH test in distinguishing isolated PT from early-stage PP in girls with early breast budding.
