About this article: This article was created by doctors to help you read and understand your pathology report for cortical inclusion cyst of the ovary. If you have any questions about this article or your pathology report, please contact us.
A cortical inclusion cyst is a non-cancerous change that is commonly seen when the ovary of a reproductive-age woman is examined under the microscope. It is a small hole that forms from a break in the tissue on the surface of the ovary. Pathologists use the word cyst to describe any abnormal open space in a tissue sample.
The break in the surface of the ovary develops when the ovum (egg) is released during ovulation. If the break does not repair fully, a cortical inclusion cyst is left behind. There can be a single cyst or multiple cysts within the ovary.
