Figure 3. (a) Coronal T₁W cranial MRI demonstrates high signal intensity of the involved cranial bones with nodular cavern-like low signal intensity areas on the frontal bone and posterior part of the parietal bone. Involvement of the maxilla and mandible is also seen. (b) On post-contrast image of the same plane demonstrates contrast enhancement of these cavern-like nodular areas. Contrast enhancement of the involved maxilla and mandible is also seen (Case 1).
