Fibrous dysplasia is an uncommon benign disease of
the bone, with slow progression. Monostotic involvement
of the paranasal sinuses is rare. We report a 54-
year-old woman who had complaints of facial asymmetry,
chronic sinusitis, recurrent headaches, and nasal
obstruction for two years. Conventional radiography
showed opacification and expansion of the maxillary
sinus. Axial and coronal computed tomography scans
showed a heterogeneous mass that expanded the right
maxillary sinus, leading to nasal obstruction and cortical
thickening of the maxilla. No signs of destruction or erosion
in the cortical bone were identified. An endonasal
endoscopic biopsy was performed and the diagnosis of
fibrous dysplasia was confirmed histologically.
