What is the most common type of ovarian tumor?

The mature teratoma is by far the most common ovarian germ cell tumor. It is a benign tumor that usually affects women of reproductive age (teens through forties). It is often called a dermoid cyst because its lining is made up of tissue similar to skin (dermis).

What is internal echoes in ovarian cyst?

The presence of solid components, papillary projections, intralesional vascularity or nodular septa is a high concern for malignancy[24,25]. In premenopausal women, cysts with uniform internal echoes, reticulations or septations may represent hemorrhagic functional cysts or an endometrioma.

Are masses on ovaries always cancerous?

Ovarian tumors are most often benign, however, some types may develop into ovarian cancer if left untreated. Symptoms are rare and tumors are usually detected during a routine pelvic exam or Pap test.

What does a mass on your ovaries mean?

Ovaries can become enlarged (masses or tumors) due to cysts (ovarian and hemorrhagic ovarian cysts), masses (endometriomas), or neoplasms (growths). The vast majority of ovarian neoplasms in girls and young women are not cancerous.

What is a bilateral tumor?

Cancer that occurs in both of a pair of organs, such as both breasts, ovaries, eyes, lungs, kidneys, or adrenal glands, at the same time.

What is a bilateral ovary?

Unilateral oophorectomy: Removing one ovary (one side). Bilateral oophorectomy: Removing both ovaries (both sides). Salpingo-oophorectomy: Removing the ovary and fallopian tube—the small organ that helps guide eggs from the ovary to the uterus.

What causes tumors on your ovaries?

What Causes Ovarian Masses and Tumors? Ovarian cysts are usually associated with hormonal stimulation and/or ovulation. Ovarian masses like endometriomas are associated with endometriosis—an inflammatory condition when the glands and stroma of the uterine lining (endometrium) are found outside of the uterine cavity.

What is the average size of an ovarian tumor?

The average measurement was 4.8 cm in advanced disease, and was 10.7 cm in early stage disease. This difference was statistically significant (p<0.001). Conclusions: Overall, patients with early stage ovarian cancer have diseased ovaries that are more than twice as large as those found in advanced disease.

How are extra axial tumors different from intra-axial tumors?

Extra-axial tumors are not derived from brain tissue and do not have a blood-brain-barrier, so most of them enhance homogeneously. The differentiation between intra-axial versus extra-axial is usually straight forward, but sometimes it can be very difficult and imaging in multiple planes may be necessary.

Where does an intra axial tumor on a T2W image show?

On the other hand, in an adult an intra-axial tumor will be a metastasis or astrocytoma in 75% of cases. The T2W-images show a schwannoma located in the cerebellopontine angle (CPA). This case nicely demonstrates the typical signs of an extra-axial tumor.

Who are the authors of intra axial brain tumors?

Intra-axial brain tumors Handb Clin Neurol. 2016;135:253-274.doi: 10.1016/B978-0-444-53485-9.00014-3. Authors Otto Rapalino 1 , Tracy Batchelor 2 , R Gilberto González 3 Affiliations

Where are most intra axial tumors ( GBS ) located?

Intra-Axial Tumors. Most GBs arise in white matter of cerebral hemispheres (frontal, temporal, parietal, corpus callosum) in males >50 years of age. Imaging studies often reveal a typical nodular rim enhancement; edema is generally present, hemorrhage may occur, calcifications are rare, and 10% occur in multiple sites.
