Patient Data

CT

A hypodense, non-enhancing lesion occupying and expanding the right frontal sinus measuring measures about 4 x 4.3 x 3.7 cm. The lesion causes remodeling of the adjacent bone.

Inferolaterally it is bulging to the right orbital cavity without evidence of significant surrounding erosive or infertility features. The right eye globe is displaced inferolaterally.

Superoposteriorly, there is thinning the upper and posterior walls of the right frontal sinus however no extension to the cranial fossa nor invasion of brain parenchyma is seen.  

Mild mucoperiosteal thickening of bilateral maxillary sinuses.

The globes show normal ocular contents. Both lenses are intact.

The eye muscles are normal. The retro-bulbar fat is unremarkable.

Case Discussion

Paranasal sinus mucoceles represents complete opacification of paranasal sinus(es) by mucus. It is often associated with bony expansion due to obstruction of the nasal sinus drainage.
