Enostosis

An enostosis is a small area of compact bone within the cancellous bone.[1][2] They are commonly seen as an incidental finding on radiographs or CT scans. They are typically very small and do not cause any symptoms.[3] Their radiodensity is generally similar to cortical bone.[4] No treatment is necessary. Multiple enostoses are present in osteopoikilosis.[5]
