A corpus luteum cyst is a type of ovarian cyst which may rupture about the time of menstruation, and take up to three months to disappear entirely. A corpus luteum cyst rarely occurs in women over the age of 50, because eggs are no longer being released after menopause. Corpus luteum cysts may contain blood and other fluids. The physical shape of a corpus luteum cyst may appear as an enlargement of the ovary itself,  rather than a distinct mass -like growth on the surface of the ovary. Signs and symptoms
Corpus luteum cysts are a normal part of the menstrual cycle. They can, however, grow to almost 10 cm (4 inches) in diameter and have the potential to bleed into themselves or twist the ovary, causing pelvic or abdominal pain. It is possible the cyst may rupture, causing internal bleeding and pain. This pain typically disappears within a few days of the rupture. If the corpus luteum becomes large it may cause ovarian torsion, where the ovary twists and blood flow is cut off. Ovarian torsion is rare and is accompanied by severe pain. Pathophysiology
This type of functional cyst occurs after an egg has been released from a follicle. The follicle then becomes a secretory gland that is known as the corpus luteum. The ruptured follicle begins producing large quantities of estrogen and progesterone in preparation for conception. If a pregnancy doesnt occur, the corpus luteum usually breaks down and disappears.
A person with disorganized schizophrenia may also experience behavioral disorganization, which may impair his or her ability to carry out daily activities such as showering or eating.The emotional responses of such people often seem strange or inappropriate. Inappropriate facial responses may be common, and behavior is sometimes described as "silly", such as inappropriate laughter. Sometimes, there is a complete lack of emotion, including anhedonia (lack of pleasure), and avolition (lack of motivation). Some of these features are also present in other types of schizophrenia, but they are most prominent in disorganized schizophrenia. Treatment
This form of schizophrenia is typically associated with early onset (often between the ages of 15 and 25 years) and is thought to have a poor prognosis because of the rapid development of negative symptoms and decline in social functioning.Use of electroconvulsive therapy has been proposed; however, the effectiveness after treatment is in question.
