Malignant Ovarian Cyst Ovarian Cancer Ultrasound Color Doppler

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 cancer is a silent killer. Aydin tekay pentti jouppila controversies in assessment of ovarian tumors with transvaginal color doppler ultrasound acta obstetricia et gynecologica scandinavica 10 3109 00016349609033324 75 4 316 329 2011. An important goal of ovarian evaluation by ultrasound is to determine the differences between normal physiologic. 23 since transvaginal ultrasound can consistently detect 8 ml or more of cul de sac fluid no fluid is.

Question 8 is measurable fluid in the cul de sac. However improvements in identification of women at high risk for ovarian cancer as well as improved imaging techniques have increased the likelihood of early detection. The use of doppler analysis for the purposes of color flow mapping and characterization of waveforms has been used to evaluate neovascularity of ovarian neoplasms often combined with other ultrasound markers 10 12 17 20. Ultrasound or precisely tvus can easily miss out a lump or mass in the ovary during the screening which could potentially be the cancerous tumor.

Compare the gray scale and color doppler ultrasound features of ovarian cancer arising in endometrioid cysts with those of benign endometrioid cysts. A post menopausal patient has 5 5 7 8 ml of cul de sac fluid depending on the degree of ovarian activity. Even those can detect mass or tumor in the ovary but not confirm whether the lump is malignant cancerous. 1 2 3 primary ovarian fallopian tube and peritoneal high grade serous ovarian cancer hgsoc high grade serous ovarian cancer is the most prevalent and lethal histologic subtype of.

As the ovaries become atrophic the production of cul de sac fluid declines. These rules apply to masses that are not a classical ovarian mass e g. Corpus luteum endometrioma dermoid cyst which have pathognomonic imaging features. The negative predictive value of color doppler sonography was 98 whereas the positive predictive value was 83.

The prevalence of solid tissue with positive doppler signals was higher in malignant tumors 100 than in benign cysts 7 8 p 0 0001. Ground glass appearance of a hemorrhagic ovarian cyst. Power doppler signals were detected within the. Thus ultrasound can miss out on ovarian cancer lumps.

In order to verify whether an ovarian endometrioid location could represent a particular setting of ovarian masses more likely to harbor diagnostic uncertainties we were prompted to.
