Case 1. Case 1. Images in a 51-year-old man with a history of painful maxillary swelling caused by GCG.A, Contrast-enhanced axial CT image demonstrates an expansile lesion arising from the anterior and inferior left maxilla, with heterogeneous enhancement and soft tissue seen anterior to the maxilla.B, Bone algorithm–correlating image demonstrates the osseous expansile changes, with thinning of the anterior wall and central foci of increased attenuation consistent with mineralization seen with GCG.
