- CT showed a heterogeneously expanded left occipital bone.
- MRI showed the lesion to have mixed signal intensity on diffusion-weighted and T2-weighted imaging and patchy enhancement.
- Fibrous dysplasia involving multiple bone of the skull in the context of McCune-Albright syndrome.
- The expansile lesion in the sphenoid bone has a ground-glass texture on CT.
- On MRI, the lesion was hypointense on all sequences.
- 45-year-old patient presented with a longstanding skull deformity.
- CT showed an expansile lesion centered on the left temporal bone with the ground glass texture that is classic for fibrous dysplasia.
