A 26 year old man came with the complaints of asymmetrical enlargement of the right half of the face.
The CT scan of the skull shows dysplastic growth of bones over the right side of the face causing asymmetrical enlargement. Multiple craniofacial bones are involved . These show expansive growth without any breach in the continuity of the cortex. Some areas show 'cystic' components others have a 'ground glass' appearance.
