Management of asymptomatic ovarian and other adnexal cysts imaged at us The international ovarian tumor analysis (iota) group ultrasound rules for ovarian masses are a simple set of ultrasound findings that classify ovarian masses into benign, malignant or inconclusive masses.

Ovarian cystic neoplasms can be either benign or malignant and can arise from epithelial, stromal, or germ cell components
In general, the risk of malignancy in unilocular cystic tumours <10 cm in women over the age of 50 years is thought to be low 3,4.
Malignant ovarian lesions can have typical sonographic features, and thus ultrasound is the imaging of choice for initial evaluation of suspected ovarian neoplasm Radiographic features the features of malignant ovarian neoplasm on ultrasonography include Solid tumor mass >10 cm with loculation mural nodule thick and irregular walled cyst cyst with thick septae (>3 mm) poorly defined margins. Terminology the terms ovarian cyst and ovarian follicular cyst are often used interchangeably
These two terms describe lesions >3 cm, and it is important to differentiate them from an ovarian follicle which is <3 cm Epidemiology they present in women of reproductive age Clinical presentation they are asymptomatic and frequently present on routine pelvic scans Hemorrhagic ovarian cysts usually result from hemorrhage into a corpus luteum or other functional cyst
Radiographic features are variable depending on the age of the hemorrhage
They typically resolve within 8 weeks
