Mature teratomas of the ovary, known as dermoid cysts, are the most common ovarian tumors among women under 45 years of age. The average age of their identification is around 30 years; they are rarely diagnosed before puberty. They make up 5 to 25 percent of all ovarian tumors on average 20 percent. Nonthreatening dermoid cysts account for 95 per cent of ovarian tumors of germinal origin. The majority of dermoid cysts are asymptomatic. Sometimes, they manifest by discomfort, pelvic pain and compressive pain of the lower abdomen. The most frequent complication is cyst twisting, which often occurs on cysts up to 11 cm or more in size, and occurs through a combination of two factors: The heaviness of these cysts, and the lengthening of their pedicles due to their weight. They are evoked in imaging in front of the presence of a cystic formation containing grease.
