Figure’s legend
Figure 1: (A) Panoramic radiography, lower limit of the right maxillary osteolytic image (white arrows) with the presence of intra-lesional calcifications (white arrowheads). (B) Blondeau incision, total filling of the right maxillary sinus (black star) with upward displacement of the orbital floor (black arrowheads).(C-D) Axial CT sections, osteolytic image with displacement and thinning of the outer cortex without rupture (white arrows), presence of peripheral calcifications (white arrowhead). (E-F) Coronal CT sections, osteolysis affecting the nasal cavities (white star) and displacement of the orbital floor (black arrowhead). (G) Coronal CT section, three levels of density measurement within the lesion (circles 1,2,3), density 1: 808 HU, density 2: 10.7 HU and density 3: 708 HU. (H) Microscopic observation at low magnification showing the epithelial lining of the cystic wall (black arrows). (I) At high magnification: presence of calcifications (dashed black arrows).
