What is a thyroid tumor on ovary?

Struma ovarii is a rare ovarian tumor that was first described in 1899. It is defined by the presence of thyroid tissue comprising more than 50% of the overall mass. It most commonly occurs as part of a teratoma, but may occasionally be encountered with serous or mucinous cystadenomas.

Can ovarian cyst cause thyroid problems?

Both ovarian enlargement and ovarian cysts are associated with hypothyroidism. A decrease in ovarian volume, resolution of ovarian cysts and reversal of the polycystic ovary syndrome-like appearance, together with improvement in serum hormone levels, has been shown to occur after the achievement of euthyroidism (11).

Can a CT scan see ovarian cysts?

Ovarian cysts can sometimes be detected during a pelvic examination, although an imaging test, usually a pelvic ultrasound, is necessary to confirm the diagnosis. Computed tomography (CT) scan or magnetic resonance imaging (MRI) are also sometimes used, but less commonly.

Do ovarian cysts show up on CT?

Hemorrhagic ovarian cysts before rupture often appear unilocular on CT images, with an internal attenuation of 25–100 HU. Fluid-fluid levels and hemoperitoneum may be observed after cyst rupture.

What percent of ovarian masses are cancerous?

Among the ovarian neoplasms, 87.8 % were benign and 10 % were malignant.

What is the imaging appearance of ovarian tumors?

The imaging appearance of ovarian tumors ranges from cystic to solid masses. Although ovarian tumors have similar clinical and radiologic findings, predominant or specific key features are present in each type of ovarian tumor. 1. Serous cystadenoma is a thin-walled, unilocular or multilocular tumor filled with serous fluid.

What is the role of computed tomography (CT) in ovarian cancer treatment?

Primary prevention and early detection are crucial to increasing the chances for survival. In cases of ovarian cancer, computed tomography (CT) can provide staging information for preoperative planning and determination of surgical resectability, demonstrate tumor response to therapy, and allow detection of persistent or recurrent disease.

What does adenocarcinoma of the ovary look like on CT?

(26) Adenocarcinoma of the ovary. CT scan shows multiple soft-tissue nodules in the subcutaneous tissue and skin of the right gluteal region (open arrows), with an ill-defined mass involving the right gluteus maximus muscle. Adenopathy along the right pelvic side wall is also seen (solid arrow). Figure 27.

What are the limitations of CT and MR imaging for ovarian cancer?

A major limitation of both CT and MR imaging is relatively poor sensitivity for detection of small tumor implants, especially on the small intestine or mesentery (, 26,, 28 ). This limitation is related to the natural history of metastatic ovarian cancer.
