What is ovarian adenoma?

Ovarian cystadenoma is a manifestation of ovarian tumor. It is mainly caused by the retention of secretions in the glandular duct, which gradually expands, thus leading to the disease of cystadenoma. It is relatively harmful to women's health. In addition to being prone to appearing in the ovaries, it is also prone to appear in the pituitary gland, thyroid gland, breast and other parts. It can usually be detected by ultrasound.

1. Causes

Due to the accumulation of glandular secretions in the cystadenoma, the glandular cavity gradually expands and fuses with each other, and cystic cavities of varying sizes can be seen with the naked eye. Cystadenomas usually occur in the ovaries and occasionally in the thyroid and pancreas. There are two main types of ovarian cystadenomas: one is that the glandular epithelium grows in a papillary shape into the cystic cavity and secretes serous fluid, so it is called serous papillary cystadenoma; the other secretes mucus, is often multilocular, has a smooth cystic wall, and rarely has papillary hyperplasia.

2. Common parts

Adenomas are common in endocrine glands such as the breast, pituitary, thyroid, ovaries, and in the stomach, intestines, and liver. It develops slowly, forming localized nodules with a polyp-like or papillary surface. It is composed of cuboidal or columnar epithelial cells similar to normal glandular cells. The cells are arranged in a very regular pattern, with a clear boundary between the intrinsic membrane and the surrounding connective tissue.

3. Ultrasound manifestations

Serous papillary cystadenoma:

1. The tumor "cross-section" is round or oval, with multiple or single rooms;

2. The cyst wall is still smooth, but there are localized light spots of varying sizes or papillary light mass structures protruding into the cyst wall;

3. There are often sandy calcified bodies between the papillary protrusions, which appear as obvious strong echo spots. In addition, spontaneous rupture of the cystadenoma may cause ascites.
