“RANULA”

This is a retention cyst arising from the sublingual gland. 
The simple type is confined to the sublingual space; the diving type extends to the submandibular space.
MRI

•  Best demonstrated on T2 sequences. Look for a fluid signal lesion in the sublingual space (simple) or extending to the submandibular space (diving).
•  Thick wall enhancement suggests infection.
