From the case:

There is an expansile ground-glass lesion with a homogeneous matrix obliterating partially the right maxillary sinus and extending to the alveolar processes. No osteolytic or soft tissue component is seen.
From the case:
Fibrous dysplasia - maxilla
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/107664/annotated_viewer_json?lang=us"}
On MRI sequences this maxillary lesion appears of intermediate signal on T1, low signal on T2 and FLAIR with moderate enhancement. No soft tissue component is seen.
Case Discussion
The CT features are most consistent with fibrous dysplasia of the right maxilla.
MRI is not particularly useful in differentiating fibrous dysplasia from other entities as there is marked variability in the appearance of the bone lesions.
