Is ranula a Mucocele?
Ranulas are mucoceles that occur in the floor of the mouth and usually involve the major salivary glands. Specifically, the ranula originates in the body of the sublingual gland, in the ducts of Rivini of the sublingual gland, and, infrequently from the minor salivary glands at this location.
How do you treat plunging ranula?

How is central Fluid attenuated in a ranula?
Uncomplicated ranulas appear as thin-walled cystic lesions with central fluid attenuation (10-20HU). If the cysts have been intervened upon previously or have been infected, the content may be increased in attenuation, even occasionally resembling a non-enhancing soft tissue mass. The walls of such lesions are typically thicker 7.
