Fortunately, gestational sac, yolk sac and embryo ...
Gynecologic ultrasonography or gynecologic sonography refers to the application of medical ultrasonography to the female pelvic organs (specifically the uterus, the ovaries, and the fallopian tubes) as well as the bladder, the adnexa, and the recto-uterine pouch. The procedure may lead to other medically relevant findings in the pelvis.This ...
A luteoma is a tumor that occurs in the ovaries during pregnancy. It is associated with an increase of sex hormones, primarily progesterone and testosterone. [1] [2] The size of the tumor can range from 1 to 25 cm in diameter, but is usually 6 to 10 cm in diameter [3] and can grow throughout the duration of the pregnancy. [4]
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta- human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
OGCTs are commonly found during pregnancy when an adnexal mass is found during a pelvic examination, ultrasound scans show a solid mass in ovary or blood serum test shows elevated alpha-fetoprotein levels. [1] They are unlikely to have metastasized and therefore the standard tumor management is surgical resection, coupled with chemotherapy. [2]
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
In anembryonic pregnancy, levels of the pregnancy hormone human chorionic gonadotropin (hCG) typically rise for a time, which can cause positive pregnancy test results and pregnancy symptoms such as tender breasts. [2] [7] Because of the presence of hCG, an ultrasound is typically necessary to diagnose an anembryonic pregnancy. [3]
During pregnancy, they may also be the cause of miscarriage, [8] bleeding, premature labor, or interference with the position of the fetus. [9] A uterine fibroid can cause rectal pressure. The abdomen can grow larger mimicking the appearance of pregnancy. [1] Some large fibroids can extend out through the cervix and vagina. [7]
