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).
