Cervical multilocular cysts, also called nuchal glandular cysts, medically known as cervical glandular cysts, are in the majority of cases physiological changes of the cervix and usually do not require special treatment. The female uterus is inverted pear-shaped with the lower part of the cervix, which is cylindrical in shape and its cervical canal is covered with glandular epithelium with formed cervical glands that secrete mucus, while the exposed part of the cervix in the vagina is rounded and covered by a complex layer of squamous epithelium with a smooth surface. The junction of squamous and glandular epithelium is called squamocolumnar junction, and the squamocolumnar junction migrates outward (vaginal part) with the rise of estrogen, resulting in the exposure of the glandular epithelium of the cervical duct to the vagina. The cyst is formed by the retention of mucus secretions in the gland. In addition, local injury to the cervix and chronic inflammation of the cervix can also lead to narrowing of the cervical glandular ducts and the formation of cervical glandular cysts. These glandular cysts are cervical cysts. If a gynecological examination is performed and the cervix is exposed with a vaginal speculum and observed with the naked eye, or if the cervix is touched with a vaginal finger, superficial cervical cysts are easily diagnosed as single or multiple small greenish-white vesicles protruding from the surface of the cervix, while deep cysts can be examined by vaginal ultrasound, which shows no abnormality on the surface of the cervix, as cervical hypertrophy, and ultrasound suggests multiple echogenic cervical cysts. Since the majority of cervical cysts are due to physiological changes, they usually do not require special treatment. However, larger cysts need surgical removal if they prolapse out of the cervical orifice to form a polyp-like shape that is difficult to distinguish from polyps. In addition, there are reports of huge cervical cysts obstructing the cervical opening and even leading to obstruction of the fetal head during delivery, which can be treated by puncturing the cyst or removing it.
