Odontogenic keratocyst growth pattern tends to show which characteristic?

• A. It grows rapidly with large expansion.
• B. It tends to show minimal expansion despite lesion size.
• C. It always causes tooth resorption.
• D. It is always radiopaque.

Answer: (B)

Odontogenic keratocyst tends to grow within the medullary bone along cancellous spaces, so it can become quite large without causing pronounced outward expansion of the cortex. This intrabony, less-expansive growth means you may see a relatively large radiolucent lesion with minimal buccolingual expansion on imaging. That’s why this description fits best: large lesion size with only modest expansion. It isn’t radiopaque (it usually appears radiolucent on radiographs), and tooth resorption is not a universal feature, so those options don’t describe the typical pattern.
