  • (See Presentation, DDx, and Workup.)[emedicine.medscape.com]
  • If on the unenhanced-CT the density is equal to or below 10 HU the lesion is considered to be an adenoma and no further workup is neccessary If the density is more than 10 HU the wash out should be calculated.[radiologyassistant.nl]
Ovarian Mass
  • The case was managed by abdominal hysterectomy and bilateral salphingectomy of the hematosalphinx, which had formed a tubo-ovarian mass. One ovary was preserved.[ncbi.nlm.nih.gov]
  • Ovarian mass was explored out, pedicles traced and dissection of ureter done, pedicles clamped and ovarian mass was excised and sent for frozen section which reported as mucinous cystadenoma of ovary.[medcraveonline.com]
  • The majority of ovarian masses are cystic, and many of them are functional which may spontaneously resolve (2).[jmrh.mums.ac.ir]
  • mass with vascularization in some of the septations Benign cystic lesions: Mucinous cystadenoma with a septated cystic ovarian mass Benign cystic lesions: Mucinous cysteadenoma Benign cystic lesions: Mucinous cysteadenoma Benign cystic lesions: Mucinous[ultrasoundcases.info]
  • In conclusions, germ cell tumours the most important causes for the giant ovarian masses in children. Epithelial tumors should not be forgotten in the differential diagnosis Key words: Adolescent, Ovarian Cysts, Ovarian Neoplasms, Serous Cystadenoma[scopemed.org]
Multilocular Cyst
  • cysts containing fluid of various viscosity.[radiopaedia.org]
  • Cut section showed thick brownish coloured fluid oozing out from multilocular cyst was seen. Microscopic examination of serial sections revealed a cyst wall lined by tall columnar epithelium with vocuolated cytoplasm.[medcraveonline.com]
  • The cyst is usually unilocular, but it can be multilocular. Cysts are filled with clear, serous fluid [1] .[cancerwall.com]
  • The ultrasound result is scored 1 point for each of the following characteristics: multilocular cysts, solid areas, metastases, ascites and bilateral lesions.[patient.info]


  • The advances made in the treatment of gynecologic malignancies are due, in part, to the clinical studies performed by many of the contributors to this volume.[books.google.com]
  • Treatment The three basic treatment methods for ovarian cancer, including endometroid adenoma, are local surgical resection of the cancerous cells, intraperitoneal chemotherapy, (drugs are delivered directly to the affected area) and systemic chemotherapy[knowcancer.com]
  • […] differentiating malignant from benign masses Malignancies are rich in neovascularization and therefore have lower resistive and pulsatile indices Gray-scale ultrasound for diagnosis of ovarian malignancy is 62 – 100% sensitive and 77 – 95% specific Treatment[learningradiology.com]
  • Treatment and prognosis A mucinous cystadenoma is benign with excellent prognosis (c.f. borderline mucinous tumors of the ovary or mucinous cystadenocarcinoma of the ovary).[radiopaedia.org]
  • In fact, earlier diagnosis is associated with less invasive treatment approaches and prevention of tissue destruction.[jmrh.mums.ac.ir]

  • (Outcomes/Resolutions) The prognosis of Benign Mucinous Cystadenoma of Ovary is excellent with suitable treatment The prognosis is generally good when the lesions are small and found below the ovarian surface.[dovemed.com]


  • Etiology Thought to largely derive from ovarian epithelial inclusions, which itself is derived from fallopian tube epithelium. Location They can be bilateral in 15% of cases.[radiopaedia.org]
  • Diagnostic laparoscopy can be used in masses of uncertain etiology, as well. Surgery is the treatment of choice for serous cystadenomas. Unilateral salpingo-oophorectomy is commonly considered in huge tumors (7).[jmrh.mums.ac.ir]
  • Ovarian cyst is a common disorder in young women with various etiologies.[bmcresnotes.biomedcentral.com]
  • (Etiology) The exact cause of Benign Mucinous Cystadenoma of Ovary is unknown; they are thought to occur spontaneously Researchers have documented certain genetic changes within the tumor.[dovemed.com]
