Most cystic lesions of the floor of the mouth are of salivary origin, with ranulas and mucoceles being the most common. The following heterogeneous group of other masses may have a similar appearance on imaging: dermoid cysts (a term that includes dermoid, epidermoid, and teratoid cysts), infectious processes, and benign neoplasms, mainly of salivary and neural origin.1 Diagnosis is based on the findings of ultrasound, with or without fine-needle aspiration cytology, and possibly on those of computed tomography (CT) or MRI.
