Cervical plicae palmatae are normal folds seen on the anterior and posterior walls of the cervical canal. They are often described as longitudinal ridges or oblique elevations. In nulliparous women, these may have branches running laterally.
Sometimes they are identified on MRI, and one must not misinterpret this finding as abnormal. Studies report that 50% of women between the ages of 20-50 years and 25% of women are in their sixth decade of life 2.
They are thought to be a remnant of Müllerian duct fusion.
They are often mistaken as cervical septa.
