A mucocele is a distension of a hollow organ or cavity because of mucus buildup.
By location
[edit]Oral
[edit]Oral mucocele is the most common benign lesion of the salivary glands generally conceded to be of traumatic origin. It is characterized by the pooling of mucus in a cavity due to the rupture of salivary ducts or acini. It can occur in the lower lip, palate, cheeks, tongue and the floor of the mouth.
Appendix
[edit]Appendiceal mucocele is found in 0.3 to 0.7% of the appendectomies.[1] It is characterized by the dilation of the organ lumen with mucus accumulation.[1] Appendix mucocele may come as a consequence of obstructive or inflammatory processes, cystadenomas or cystadenocarcinomas. Its main complication is pseudomyxoma peritonei.[1]

Diagnosis
[edit]Superficial mucoceles can often be diagnosed by appearance and consistency alone. Sometimes, it is indicated to perform diagnostic imaging and/or needle biopsy.[citation needed]
On a CT scan, a mucocele is fairly homogenous, with an attenuation of about 10-18 Hounsfield units.[2]
