A mucocele is any dilatation (typically pathologic) with accumulation of mucus.
Superficial mucoceles can often be diagnosed by appearance and consistency alone. Sometimes, it is indicated to perform diagnostic imaging and/or needle biopsy.
On a CT scan, a mucocele is fairly homogenous, with an attenuation of about 10-18 Hounsfield units.
