Adult Female's Ovary Containing an Ovarian Cyst

Description

Centered in the female pelvis, the ovary is shown in section to expose the ovarian cortex and medulla, with a rounded, fluid-filled cyst expanding the parenchyma. A thin cyst wall displaces normal follicles toward the periphery, compressing stromal tissue and flattening the usual lobulated contour. Medially, the ovarian hilum and mesovarium attachment would be expected near the utero-ovarian ligament, while the lateral pole relates to the suspensory ligament of the ovary and its contained ovarian vessels. Clear boundaries. Ovarian cyst morphology is a daily interpretive problem in gynecology and imaging because management hinges on size, internal architecture, and the likelihood of a functional cyst versus neoplasm. A simple, unilocular, anechoic cyst on transvaginal ultrasound often represents a follicular or corpus luteum cyst, but increasing diameter, septations, mural nodules, or echogenic contents shift concern toward cystadenoma, endometrioma, or malignancy and guide follow-up with O-RADS style risk stratification. Enlarged cysts also increase the risk of adnexal torsion, where the ovary twists around the infundibulopelvic and utero-ovarian ligaments, compromising venous outflow first and producing acute pelvic pain that may require urgent laparoscopy. Use this illustration in reproductive anatomy and pathology teaching to connect gross ovarian structure with common cyst types, and in clinical education materials discussing ultrasound findings, watchful waiting criteria, and operative options such as cystectomy with ovarian tissue preservation. It also suits patient-facing counseling sheets that explain why a “simple cyst” is often observed while complex features prompt tumor marker testing and surgical referral.
