UNASSIGNED: The objective of this study was to determine the adherence of radiologists to the guideline of the Society of Radiologists in Ultrasound (SRU)-2010 for the follow-up of ovarian cysts in patients during 2015-2016.
UNASSIGNED: The patients\' data, referring for transvaginal and pelvic ultrasonography, suffering from ovarian cyst were assessed in terms of menopause status, cyst size, and type, as well as follow-ups recommended by radiologist to assess the adherence of reports to SRU-2010.
UNASSIGNED: Three hundred and sixty-four sonography reports were investigated. Seventy-seven percent of the reports had adhered to SRU-2010, 9.9% and 9.1% had under/overmanagement, and 4.1% was incomplete. 94.2% and 5.8% of cases were in pre/postmenopause status, respectively. The highest adherence belonged to cysts in size <1 cm, 1-3 cm, 5-7 cm. The highest adherence, over/undermanagement, and incomplete reports belonged to corpus luteum, hemorrhagic, dermoid cysts, and nodules without flow. The adherence of sonography reports to SRU-2010 for accidental ovarian cysts was 76.9%.
UNASSIGNED: The tendency for overmanagement of simple cysts in premenopausal women and the tendency for undermanagement in simple cysts and in postmenopausal women were higher, respectively. It is expected that more training of the guideline to radiologists will lead to the reduction of unnecessary follow-up, which in turn leads to reduced patient\'s anxiety and cost of treatment.

Transvaginal pelvic ultrasound is the first-line imaging examination for presumed benign ovarian tumors (PBOT) in adult women (Grade A). Ultrasound is sufficient for characterizing a unilocular anechoic cyst smaller than 7cm (Grade A). Magnetic resonance imaging is the recommended second-line investigation for indeterminate masses or masses larger than 7cm (Grade B). Serum CA-125 assay is not recommended for first-line diagnosis in adult women (Grade C). In women with a unilocular anechoic cyst, hormone therapy is ineffective and not recommended (Grade A). Ultrasound-guided aspiration is not recommended (Grade B). Abstention is an option in adult women with a unilocular asymptomatic anechoic cyst smaller than 10cm and no history of cancer (Grade B). If symptoms develop, laparoscopy is the gold standard for surgical treatment of PBOT (Grade A). Conservative surgical treatment (cystectomy) should be preferred to oophorectomy in pre-menopausal women without a previous history of cancer (Grade C). In cases of suspected adnexal torsion, laparoscopic surgical exploration is recommended (Grade B). Conservative treatment or detorsion without oophorectomy is recommended for pre-menopausal women regardless of the estimated torsion duration and macroscopic appearance of the ovary (Grade B). During pregnancy, expectant management is recommended for unilocular asymptomatic anechoic cysts smaller than 6cm (Grade C).
