Mucocele

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]

Other

[edit]
  • Mucocele of the petrous apex
  • Mucocele of the paranasal sinuses
  • Gallbladder mucocele

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]
