Endometrioma (also called chocolate cyst) is the presence of tissue similar to, but distinct from, the endometrium in and sometimes on the ovary. It is the most common form of endometriosis . [ 1 ] Endometrioma is found in 17–44% patients with endometriosis.
Follicular cyst, the most common type of ovarian cyst. [2] In menstruating women, an ovarian follicle containing the ovum (an unfertilized egg) normally releases the ovum during ovulation. [2] If it does not release the ovum, a follicular cyst of more than 2.5 cm diameter may result. [6] A ruptured follicular cyst can be painful. [2]
Ovarian torsion (OT) or adnexal torsion is an abnormal condition where an ovary twists on its attachment to other structures, such that blood flow is decreased. [3] [4] Symptoms typically include pelvic pain on one side. [2] [5] While classically the pain is sudden in onset, this is not always the case. [2] Other symptoms may include nausea. [2]
In stage 1c and 2 cancers, radiation therapy is used after surgery if there is the possibility of residual disease in the pelvis but the abdomen is cancer-free. Radiotherapy can also be used in palliative care of advanced cancers. A typical course of radiotherapy for ovarian cancer is 5 days a week for 3–4 weeks.
This type can form when ovulation doesn't occur, and a follicle doesn't rupture or release its egg but instead grows until it becomes a cyst, or when a mature follicle involutes (collapses on itself). It usually forms during ovulation, and can grow to about 7 cm in diameter.
These patient factors include: (1) size of cyst and whether or not it is benign or malignant, (2) patient symptoms, (3) patient age, and (4) impact of cyst on the pregnancy. [23] Benign cysts less than 6 cm are more likely to spontaneously resolve over time. Surgical treatments may be needed for serious complications due to theca lutein cysts.
PTCs may be found at surgery or during an imaging examination that is performed for another reason. Larger lesions may reach 20 or more cm in diameter and become symptomatic exerting pressure and pain symptoms in the lower abdomen. [3] Large cysts can lead to torsion of the adnexa inflicting acute pain. [3] [4]
Ovarian serous cystadenoma is a non-cancerous type of tumor of the ovary. [1] It is typically larger than 1cm in diameter and presents with signs and symptoms of a growth in the pelvis, or is discovered when investigating something else. [ 2 ]
