Overview

The Rotterdam 2003 criteria include the use of ultrasound as a diagnostic tool in diagnosing polycystic ovary syndrome (PCOS). The typical polycystic-appearing ovary may emerge in a nonspecific fashion on an ultrasound. Multiple (12+) subcapsular follicles ranging from 2 to 9 mm in diameter in a state of arrested development (‘pearl necklace’ appearance) in a single ovary is diagnostic for PCOS on ultrasound.

Ultrasound

Typical ultrasonography findings in patients with PCOS are as follows:^[1]^[2]^[3]

Two- to 5-fold ovarian enlargement; ovarian volume >10 cm³
Thickened stroma (tunica albuginea)
Thecal hyperplasia with an increase in stromal content
Multiple (12+) subcapsular follicles ranging from 2 to 9 mm in diameter in a state of arrested development (‘pearl necklace’ appearance).
A discrete androgen-producing tumor in the ovary may be present in 5% or fewer patients.
The endometrium may be hyperplastic despite low estrogen production by the follicles; this is probably due to high estrone production from the increased circulating androgens and lack of opposition by progesterone.
Clomiphene may alter results due to ovarian stimulation, resulting in multiple ovarian cysts.
