Periovarian adhesions are thin strips of non-cancerous tissue attached to the outer surface of the ovary. They are commonly seen when the ovary is examined under the microscope. A periovarian adhesion is a type of scar. It is made up of a type of connective tissue that pathologists describe as fibrotic or fibrous. Adhesions can be caused by a number of different conditions including endometriosis, infections, or previous abdominal or pelvic surgery.
The ovaries are part of the female reproductive tract. They are small organs that are attached to the uterus by the fallopian tubes. The outer surface of the ovary is lined by a thin layer of specialized tissue that forms a barrier around the outside of the ovary called the epithelium. The tissue below the epithelium is called the stroma. The outer surface of the ovary is normally smooth.
