Ovarian malignancies

Fallopian tube neoplasms are rare and frequently malignant and often confused with:

Pelvic pressure and bloating

Frequently, the only symptom of ovarian cancer is:

HER2/neu

Gene that produces a protein, which regulates normal cell growth found in breast and ovarian cancer cells. The identification of this protein enables determination of treatment options

BRCA1/BRCA2

Inherited gene mutation associated with a significant increase of breast and ovarian cancer risk

Lactate dehydrogenase

Large cystic ovarian mass with thick-walled septations; may have internal debris layering components

Serous Cystadenocarcinoma

Large multilocular ovarian neoplasm with papillary projections

Poor prognosis

Late stage diagnosis of ovarian malignancy leads to a:

10 cm^3 ; 20 cm^3

Malignancy suspicion increases with the amount of solid tissue in a complex mass and if the volume exceeds ____________ in postmenopausal woman and _____________ in premenopausal women

Dysgerminoma

Malignant tumor of the ovary arising from undifferentiated germ cells of the embryonic gonad. the tumor is historically identical to seminoma found in the testicle

Normal-sized ovaries

Menopausal females utilizing hormone replacement therapy (HRT) will demonstrate:

Common

Metastasis to the ovary is:

3-D multiplanar with surface rendering Image A demonstrated internal architecture of a simple cyst with smooth regular walls Image B shows internal wall projections into an ovarian cyst

Name the imaging technique used in these images. Describe image A and compare it to image B.

Image A - Ovary with mulitseptated cyst displaying internal projections (open arrows) Image B - Flow in the thick separating membrane (long arrows) The complex fluid and cystic septations suggest ovarian malignancy C8-4V transducer

Name the structure visualized in images A and B. Identify the struture the open arow is pointing to on image A and B. Describe what the long arrows are pointing to in image B. What transducer was used to obtain these images?

Transbadominal, transverse pelvis Small open arrow - Right ovary with simple cyst Thin arrow - Left adnexal dermoid Thick arrow - Uterus Large open arrow - Distended urinary bladder

Name the view and organs imaged. Describe what the small open arrow, thin arrow, thick arrow, and large open arrow are depicting.

Clear-cell adenocarcinoma

Neoplasm involving the surface epithelium of the female reproductive organs (ovary), which involves cells with a clear appearance on microscopic examination

Epithelial Ovarian Cancer

Neoplasm involving the surface epithelium of the ovary

Yolk cell tumor/endodermal sinus tumor

Neoplasm originating in the germ cells (ovum)

Menstruating

Nonneoplastic cystic foci of the ovary are commonly seen in ___________________ females and are difficult to differentiate from malignant lesions, so should be considered when determining the diagnosis.

Late stages of the condition

One of the most lethal forms of cancer is ovarian because it is frequently diagnosed in:

Perimenopausal and postmenopausal women

Ovarian cancer is mostly a disease of:

Dependent portion of the peritoneal cavity

Ovarian malignancy is often associated with ascites, which first accumulates in the:

Right side

Ovarian metastatic masses are usually bilateral and more common on the:

CA 125

Protein found in tumor cells that results in an elevation of blood levels

The accumulation of gelatinous material in the peritoneal cavity

Pseudomyxoma peritonei is defined as:

Sertoli-Leydig Cell Tumors/Androblastoma
