The identification of PCOS is based on clinical findings that are heterogeneous and highly variable, which makes it challenging to establish the diagnosis. However, the great variability in symptoms and clinical and biochemical manifestations of PCOS make the aetiology and pathophysiology unclear (Franks, 1994; Conway, 1996). INTRODUCTION. The morphological features of the ovaries in women with polycystic ovary syndrome (PCOS) have been well described by ultrasound imaging technology. Epub 2013 Nov 1. 5. According to the normative model developed by Kelsey et al., in the average case, the ovarian volume rises from 0.7 mL (95% confidence interval (CI) 0.4–1.1 mL) at 2 years of age to a peak of 7.7 mL (95% CI 6.5–9.2 mL) at 20 years of age with a subsequent decline to about 2.8 mL (95% CI 2.7–2.9 mL) at menopause and smaller volumes thereafter . We evaluated ovarian volume, area, stroma, and the stroma/total area (S/A) ratio by use of transvaginal pelvic ultrasound; and we assayed serum levels of gonadotropin, androgen, and estradiol during the early follicular phase (days 2 to 5) of the menstrual cycle in regularly cycling controls and on a random day in amenorrheic patients. Efforts in establishing an objective evaluation index of the follicle distribution pattern may help provide insights into the pathophysiology underlying the classic “string-of-pearls” appearance of a polycystic ovary. It is mandatory to perform ultrasound and laparoscopic biopsy. Clinical efficacy and metabolic impact of two different dosages of ethinyl-estradiol in association with drospirenone in normal-weight women with polycystic ovary syndrome: a randomized study. Given that the ovarian volume threshold values might depend on the clinical and metabolic characteristics of the population studied, the AEPS guidelines highly recommended the use of in-house reference normal values. Similarly, the stroma/total ovarian volume ratio was reported as the most accurate predictor of hyperandrogenemia and hirsutism . More recently, transvaginal ultrasound examination of ovarian morphology has been used to help make the diagnosis. Elevated concentrations of the angiogenic factors including vascular endothelial growth factor, angiopoietins, and basic fibroblast growth factors were also observed in the serum and/or follicular fluid of women with PCOS during controlled ovarian hyperstimulation and may play an important role in the increased risk of ovarian hyperstimulation syndrome in PCOS . In adult women, a linear pattern of decline was also observed in follicular number and anti-Müllerian hormone (AMH), both remaining higher in subjects of PCOS compared to the adult controls at all ages . A longitudinal study of the ovarian volume in PCOS patients showed that the decrease in ovarian volume with age was less pronounced in premenopausal women with PCOS. With the advance of imaging technology, numerous efforts have been made to define the ovarian appearance in women with PCOS and the ultrasound criteria of PCOM have been refined over time. The ovarian stroma appears hyperechogenic (stromal score = 2). The criterion of >12 follicles per ovary for diagnosis becomes obsolete. evaluation of ovarian torsion. If there is reason to suspect you have ovarian cancer based on your symptoms and/or physical exam, your doctor will order some tests to check further. 2020 Sep;160(3):R25-R39. Your doctor will ask about your medical history to learn about possible risk factors, including your family history. Ultrasound diagnosis of polycystic ovary syndrome. The results may be explained by folliculogenesis disorders: excessive early follicular growth and/or follicle arrest . tissue (e.g. At this late stage, ovarian cancer is more difficult to treat. Fulghesu AM(1), Ciampelli M, Belosi C, Apa R, Pavone V, Lanzone A. 2015 Dec;21(3):149-54. doi: 10.6118/jmm.2015.21.3.149. Baillieres Clin Endocrinol Metab. The varied imaging features and nonspecific symptoms of ovarian torsion can lead to a delay in identification, with misdiagnosis being common. Ultrasound identification of the presence of polycystic ovarian morphology (PCOM) has been recognized as a component of PCOS diagnosis. The 2 tests used most often (in addition to a complete pelvic exam) to screen for ovarian cancer are transvaginal ultrasound (TVUS) and the CA-125 blood test. Cystic struma ovarii: a rare presentation of an infrequent tumor. It was the first report to link ovarian pathology with clinical hyperandrogenism and oligoamenorrhea. Antral follicles measure 2–9 mm in average diameter and increased antral follicle number per ovary (FNPO) is a key and consistent morphological feature of polycystic ovary. Increased ovarian stromal blood velocity may be a new parameter to assist in the ultrasound diagnosis of PCO. Transabdominal US images from a 9 yr old girl with torsed Lt ovary. Swanson et … Furthermore, Webber et al.  |  Transvaginal ultrasound guided ovarian stroma hydrocoagulation (TOSH) in an office setting seems to be a safe, economic and practical procedure that is acceptable by the patients. The hyperechogenic stroma is less pronounced a b 97/071 Color Doppler and hormone correlations with PCOS Battaglia et al. However, no standardized method to assess this morphological feature exists. Recently, the technique of spatiotemporal image correlation (STIC) and high-definition flow (HDF) were also introduced . 2006 Sep;65(3):396-401. doi: 10.1111/j.1365-2265.2006.02611.x. The subsequent follicular arrest is the failure of follicle development to proceed beyond the mid-antral stage, giving the characteristic appearance of multifollicular ovaries on ultrasound . Further ultrasound studies of different follicle cohorts, which may be facilitated by 3D technique, are warranted to substantiate the hypothesis of intrinsic aberrant folliculogenesis in PCOS patients. In PCOS, follicular growth is arrested at the antral follicle stage, thereby resulting in excessive antral follicle counts (AFCs). The evaluated ultrasound criteria of PCO were as follows: the presence of 12 or more 2–9-mm ovarian follicles; a peripheral distribution of ovarian follicles; an ovarian volume of more than 10 cm 3 and a highly echogenic ovarian stroma . myometrium or ovarian stroma) Note, the presence of flow (that can be confirmed with spectral Doppler if necessary) is diagnostic of solid tissue; the absence of flow is less helpful and the lesion may then be considered solid-appearing, depending on other features Also judged by its echogenicity, size, and by the The lower discriminatory power of the ovarian volume may reflect the greater likelihood of overlap among controls and PCOS patients . Polycystic ovary syndrome (PCOS) is a common endocrine disorder of unknown etiology, affecting 6–8% of reproductive-aged women . Other morphological features, although not included in the diagnostic criteria, should also be considered when determining the presence of a polycystic ovary. Author information: (1)Department of Obstetrics and Gynecology, Universitá Cattolica del Sacro Cuore, Rome, Italy. Retrospective data analysis. Gray-scale ultrasound findings include an enlarged ovary, ovarian mass, free fluid, follicles at the periphery of an enlarged ovary, thickening of a cyst wall, and a twisted pedicle [2, 3].A unilaterally enlarged ovary with central afollicular stroma and multiple uniform 8?? Alviggi C, Conforti A, De Rosa P, Strina I, Palomba S, Vallone R, Gizzo S, Borrelli R, Andersen CY, De Placido G, Guerriero S. Front Endocrinol (Lausanne). SCSTs are rare. Diagnostic criteria for PCOS: Is there a need for a rethink? Although ovarian stromal hypertrophy is related to the ovarian androgenic dysfunction, the question remains whether the parameters of ovarian stroma volume yield additional information for PCOS diagnosis.  |  With the advance of ultrasound technology, new definition has been proposed recently. Carvalho RB, Cintra ML, Matos PS, Campos PS. In the GCP, “microcysts” occupied the entire parenchyma of the ovary ( Fig. The diagnostic values of ovarian stromal size have been evaluated by a number of studies using 2D/3D techniques. J Ultrasound Med. The S/A ratio was positively correlated with the testosterone and androstenedione levels . The criterion of FNPO is crucial in guiding clinical diagnosis and further research work. Ovarian cancer is a type of cancer that begins in the ovaries. B: Absent intra-ovarian vascularity by Color Doppler US. Increased stromal echogenicity is a characteristic feature of the polycystic ovaries. Prevention and treatment information (HHS). 2017 May 31;8:117. doi: 10.3389/fendo.2017.00117. Editor’s Note: Within 8 years of menarche, the presence of many follicles within the ovary is generally considered a normal finding and ultrasound should not be used to diagnose PCOS (Dewailly, 2011; Lujan, 2013; Teede, 2019). To confirm stromal ovarian hyperplasia, doctors conduct differential diagnosis with fibroma, cancer processes or stromal endometrial sarcoma. The 2003 Rotterdam consensus ultrasound criteria of polycystic ovarian morphology (PCOM) proposed the presence of ≥12 follicles measuring 2–9 mm in diameter and/or increased ovarian volume (>10 cm 3 ) in a single ovary or both ovaries . Polycystic ovary syndrome (PCOS) is the most frequent disorder of ovarian function in women of reproductive age (Franks, 1989). The stromal area, stromal/total area ratio (S/A), stromal volume, and stroma/total ovarian volume ratio were found to be significantly higher in PCOS patients than controls . The arterial RI derived from the spectrum of ovarian stroma and uterine arteries on each side were calculated separately. Since the widespread use of transvaginal ultrasound to diagnose polycystic ovary syndrome (PCOS), a cardinal feature has been shown to be the presence of a bright, highly echogenic stroma. In addition, the number of follicles of size 2–5 mm was found to be positively correlated with the serum testosterone and androstenedione levels in PCOS patients, thereby supporting the hypothesis that the increased number of smaller follicles is associated with the trophic effects of androgens . Although the 3D (three-dimensional) method of measuring the ovarian volume avoids the use of geometric assumption, it is not recommended due to the technical and interobserver variability . The 2014 AEPS guidelines recommend that the threshold of follicle number per ovary (FNPO) be increased to 25 with the technology available for optimal resolution (mainly transducer frequency ≥8 MHz) . COVID-19 is an emerging, rapidly evolving situation. The S/A ratio showed the most significant correlation with the androgen levels. At this stage, however, PCOS remains the term that is widely known and used. Comparison of the numeric variables between different studies would be possible until a standard machine setting for 3D Doppler measurement is adopted universally . They start in the stroma or the sex cords. In 1935, Stein and Leventhal reported a case series of seven women characterized by oligomenorrhea or amenorrhea, hirsutism, and enlarged bilateral cystic ovaries found at laparotomy . It is also associated with long-term complications including endometrial carcinoma, metabolic syndrome, and cardiovascular disease. J Menopausal Med. Ultrasound Obstet Gynecol. NIH In addition, polycystic ovaries are common in young healthy women with a prevalence of 20–30% in women younger than 36 years . There is, however, a paucity of data for the ovarian morphology in normal and PCOS adolescents. The stoma cells are distributed in such a way that the tissue appears to be whorled. Ovarian stromal hyperthecosis (SH) has variable clinical importance but can cause hyperan- drogenism, particularly in premenopausal women. In the latter study, the cutoff value is 25 follicles if women with isolated PCOM were included in the control group. The different patterns of follicle distribution with the ovary may reflect different pathophysiological process of disturbed folliculogenesis . Moreover, the stroma appears increasingly bright and the blood flows at a considerably higher speed in polycystic ovaries than in normal ovaries because of the rich blood supply. While the accuracy of the updated threshold awaits further validation, it provides a new starting point for future PCOS studies. Meigs syndrome: consists of ovarian fibroma with ascites and a pleural effusion; fibromas are seen in 75% of patients with nevoid basal cell carcinoma syndrome 1; Radiographic features Ultrasound. The sonographic finding was supported by the evidence from an experimental study of histological ovarian sections that ovaries from PCOS showed a twofold increase in blood vessel density in both superficial cortical stroma and deep cortical stroma with respect to the age-matched controls . High stromal vascularity is one of the characteristics observed in the polycystic ovary which may contribute to the hyperechoic appearance of the stroma ( Fig. What are sex cord stromal tumours? found a sixfold increase in the number of primary follicles in cortical biopsies from polycystic ovaries in anovulatory women than in normal ovaries . It is similar to the results obtained by Dewailly et al. A: Note the enlarged Lt ovary in the absence of masses, its maximum dimension was 6.2 cm, as well as the free pelvic collection (yellow arrow), the tiny peripherally arranged follicles and the central afollicular stroma. Whether a larger follicle pool in PCOS patients observed in these findings is due to the prolonged survival of PCOS follicle remains unclear . described a scoring method to determine the distribution patterns by evaluating the largest cross-sectional plane (contains ≥9 follicles) of each ovary: 1 = clear follicle aggregation around the periphery with ≤1 central follicle, 2 = follicle aggregation around the periphery with >1 central follicle, and 3 = follicle scattered throughout the ovarian stroma . 30-1). Compared to FNPO, the threshold of 26 follicles had the best compromise between sensitivity (85%) and specificity (94%). The ultrasound features of the polycystic ovary in adults are presented. 2 A). These data confirm the presence of an initial excessive early follicular growth and suggest that the abnormalities of folliculogenesis occur at early stages of follicle development. In the PCP, “microcysts” were aligned in the subcapsular region of the ovary ( Fig. In 2014, the Androgen Excess Society and Polycystic Ovary Syndrome Society (AEPS) guidelines recommended using FNPO (follicle number per ovary) ≥25 for the definition of PCOM when using the newer technology that affords maximal resolution of ovarian follicles (i.e., transducer frequency >8 MHz). The women with PCOS were found to reach menopause 2 years later than the normoovulatory women . Report of 8 cases. On ultrasound, fibromas most commonly manifest as solid, hypoechoic masses with ultrasound … These include enlarged ovary size, multiple small follicles of similar size, increased ovarian stromal volume and echogenicity, peripheral distribution of the follicles, and higher stromal blood flow. The high prevalence of the polycystic ovary has further reduced the importance of the ultrasound criteria and raised doubts on its precision. The finding of small antral follicle excess was consistent with the histological observation that the contrast of follicle number between PCOS ovaries and control ovaries was best defined in the smaller tertiary follicles of diameter <4 mm . The mean FNPO of follicles 2–5 mm in size was shown to be significantly higher in polycystic ovaries than in controls, while it was similar within the 6–9-mm range between the two groups. doi: 10.1530/REP-19-0501. If larger studies confirm its effectiveness it may be an attractive alternative to conventional ovarian drilling. Furthermore, this ultrasound parameter is strictly related to hormonal milieu and to anthropometric characteristics. This site needs JavaScript to work properly. To evaluate whether some ultrasound parameters of ovarian morphology can discriminate between control women and patients with polycystic ovary syndrome (PCOS). Main outcome measure(s): The ovarian volume is calculated by 2D (two-dimensional) ultrasound using the formula for a prolate ellipsoid: volume = π/6 × length × width × thickness of the ovary ( Fig. Although the polycystic appearance of the ovaries was part of the original disease description, it is not considered as a specific pathological entity, which may also be seen in other endocrine disorders . Follicle number, not assessments of the ovarian stroma, represents the best ultrasonographic marker of polycystic ovary syndrome. Fertil Steril. Polycystic ovaries (PCO) have been reported to occur in about 20% of the general female population (Polson et al., 1988) and in up to 50% of women presenting to infertility clinics (Jacobs, 1987). This results in the counting of more antral follicles and thus a major but artificial increase in the prevalence of PCOM in normal populations. The non-PCOM women with oligoamenorrhea had signs of less severe endocrine disturbance and 33% of them had normal LH, normal LH/FSH (follicle-stimulating hormone), and androgen levels, thereby suggesting a potential hypothalamic cause of amenorrhea .
