Most of the cysts are cervical glandular cysts in the cervical canal. In most cases, cervical glandular cysts are due to physiological changes in the cervix, in the process of replacing the columnar epithelium with squamous epithelium in the transformation zone of the cervix, the new squamous epithelium covers the mouth of the cervical glandular canal or penetrates deep into the glandular canal, blocking the mouth of the glandular canal and causing obstruction of the drainage of glandular secretions and retention of cysts. Local injury to the cervix or chronic inflammation of the cervix that narrows the opening of the glandular ducts can also lead to the formation of cysts in the cervix. Cervical glandular cysts in the cervical canal, that is, deep cervical glandular cysts, are not visible as abnormalities on the surface of the cervix and appear as cervical hypertrophy, and are only visible during gynecologic ultrasound. Superficial cervical cysts are easily diagnosed when single or multiple small greenish-white vesicles are seen protruding from the surface of the cervix on examination. Myometrial cysts usually do not require treatment and only require regular annual cervical cancer screening.
