What does well-corticated mean?

Well-corticated refers to a structure, often in a medical imaging context, that has a distinct, well-defined outer layer or border, known as the cortex. This term is commonly used to describe bone lesions or cysts that have a clear, thin line of bone surrounding them, indicating a stable and non-aggressive process. In general, well-corticated features tend to suggest a benign nature, as opposed to poorly defined or irregular borders which may raise concerns for malignancy or other pathological processes.
