Right eyelid swelling and pain.

Patient Data

Age: 70 years
Gender: Female
CT

 Right frontal sinus expansion with relatively high attenuation content, it shows bony erosion in anterior and inferior boundaries, extends subcutaneously and into right orbit extraconal, causing regional mass effect and slightly displacing right globe downward.

MRI

There is an expansion of the right frontal sinus showing hypointense T1W signal. The abnormality is hyperintense on T2W and FLAIR sequences. It shows restricted diffusion with marginal contrast enhancement. It extends subcutaneously anteriorly into right eyelid, and inferiorly into right orbit. Extraconal compression is present with displacement of the superior oblique complex muscles downward.

There is slight expansion and enhancement of superior and rectus muscles.

The left frontal sinus is partially opacified.

Case Discussion

Expansion and opacification of the right frontal sinus with bony erosion and intraorbital extension likely right frontal mucocele and subperiosteal abscess with orbital extention, suggestive of a Pott puffy tumor.
