such as torsion of the ovary or intracystic bleeding. Uncomplicated cysts typically appear as a unilocular, thin-walled cystic mass (Fig. 24.1).Ovarian cystsmay appear as a complex mass (with internal echoes, septations, or debris;Fig. 24.2) or as a solid mass when complicated by...
Most of the cysts are benign ovarian cysts (non-cancerous). However, a type called mature cystic teratomas or dermoids is a non-cancerous (benign ovarian cyst) that accounts for over 10% of all ovarian growths. Para ovarian cysts occur in the broad ligament between the fallopian tube and...
and mature cystic teratomas. Important aspects of a preoperative evaluation to assist in evaluating for a potentially malignancy ovarian mass include a detailed medical history, physical examination, imaging studies, and laboratory evaluation. Fertility-sparing ovarian cystectomy, typically performed laparoscopi...

An MRI score of 2 was assigned if the reader diagnosed a purely cystic mass (ie, adnexal unilocular cyst with simple fluid and no solid tissue), a purely endometriotic mass (ie, adnexal unilocular cyst with endometriotic fluid and no internal enhancement), a purely fatty mass (ie, ...
Ovarian cancer (OC) remains one of the most lethal gynecological malignancies globally. Despite the implementation of various medical imaging approaches for OC screening, achieving accurate differential diagnosis of ovarian tumors continues to pose signi
outperformed the radiomics (AUC = 0.78) and clinical models (AUC = 0.81), respectively. Within the range of NEOC, sex cord-stromal tumor (SCST) typically present as solid masses; however, diagnostic challenges may frequently arise if necrosis, bleeding, edema, or cystic degeneration is...
(a) Axial T1WI reveals an inhomogeneous cystic mass with mostly isointensity in the right adnexal region. (b) On sagital T2WI, the cystic component of the tumor is homogenous hyperintensity, while the debris of hemorrhagic components are iso-hypo intensity, morphologically mimicking vegetations on ...
A 50-year-old woman presented with lower abdominal pain during her menstrual period for the past two months. She had a previous medical history of uterine adenomyomectomy, ovarian cystectomy, and a cesarean section. Ultrasound revealed a 5.7 × 3.8 × 4.3 cm mass on the posterior ...
