Cervical plicae palmatae are normal folds seen on the anterior and posterior wall of the cervical canal. They are often described as longitudinal ridges or oblique elevation.
Sometimes, they are identified on MRI, and one must make sure not to misinterpret this finding as abnormal. Studies report it in 50% of women between 20-50 and 25% of women in their 50s 2.
They are thought to be a remnant of Müllerian duct fusion.
History and etymology
"Plicae palmatae" is Latin for "leaf-shaped fold".
