Risk Assessment of Second Multiloculated Septated Ovarian Cyst in Postmenopausal Women

Risk Assessment Based on Cyst Characteristics

Multiloculated septated ovarian cysts in postmenopausal women require careful evaluation as they fall into a higher risk category than simple cysts 1, 2
According to the O-RADS US risk stratification system, septated cysts without solid components in postmenopausal women should be considered for further evaluation by a US specialist, gynecologist, or MRI 1, 3
While hemorrhagic cysts should not typically occur in postmenopausal women, other types of septated cysts like dermoid cysts or endometriomas can occur and may have similar appearances on follow-up imaging 2

Evaluate cyst size, internal architecture, and compare with previous imaging 1, 3
Note any changes in morphology, size, or vascularity compared to the previous stable cyst 2

Changes in morphology or developing vascular components within the lesion significantly increase the risk of malignancy 2
The risk of malignant transformation is higher in certain types of cysts in postmenopausal women, particularly endometriomas (which can transform to clear cell and endometrioid carcinomas) 1, 2
Cyst size >10 cm increases risk and warrants gynecologic consultation regardless of other features 4

For multiloculated septated cysts <10 cm without solid components that appear similar to previous stable cysts, consider annual US follow-up when not surgically excised 2
Monitor for changes in morphology, size, or vascularity 1, 2
For cysts with changing morphology or developing vascular components, direct referral for MRI is recommended 2
Gynecologic oncology consultation should be considered 4

Not comparing current imaging with previous studies to detect subtle changes that might indicate malignant transformation 2
