"T1 C+ (Gd): enhancement, if present, only occurs at the periphery"
"DWI: variable"
"The content of the mucocele is variable, and this impacts on the imaging appearances (see below). Most simple mucoceles are formed by clear thick mucus. If the mucocele has been infected (pyocele) then the content is similar to pus."
"Skull radiographs do not have a significant role to play in the diagnosis of mucoceles. If obtained, they demonstrate opacification and expansion of the affected sinus."

"MRI signal intensity is highly variable and depends on the proportions of water, mucus and protein 1-3:"
"In general, drainage and marsupialisation of an affected sinus are sufficient. If large bony defects are present, reconstructive surgery may be necessary (e.g. of the orbital floor). If drainage remains impaired, the mucocele may recur."
"There is often little differential, if any, provided that contrast material has been administered. The differential includes:"
