Case Discussion

The term ranula is derived from the Latin word for frog. It describes the cystic space beneath the tongue being like the pouch/underbelly of a frog. It represents a mucocele in the floor of the mouth. The MRI signal within it is typically high on T2-weighted images due to the mucin content.
