Teenager with Cystic Swelling in the Floor of the Mouth

Abstract

A 15-year-old girl presented with complaint of progressively increasing swelling in the right side of the floor of mouth for the past one and half month. It was not associated with pain, but patient had difficulty in swallowing and mastication. On examination, there was a dome shaped, painless, bluish, well-circumscribed, fluctuating, non-compressible cystic swelling measuring 3.5 × 3.0 cm on the right side of the floor of mouth, pushing the lingual frenulum to left side and causing elevation of tongue (Fig. 1). Contrast-enhanced computed tomography showed a thin-walled cystic lesion at the floor of the mouth (Fig. 2) without any obstruction or cervical extension, suggesting a diagnosis of ranula.
