A Rare Ventral Tongue Presentation of a Lingual Thyroglossal Duct Cyst in an Infant: A Case Report

Lingual thyroglossal duct cysts (TGDCs) represent the rarest form of thyroglossal duct cysts. We describe a four‑month‑old female who presented with a mid‑anterior ventral tongue swelling noted since birth. Magnetic resonance imaging (MRI) showed a well‑defined, non‑enhancing cystic lesion arising from the ventral surface of the tongue. Needle aspiration under sedation, followed by oral intubation and transoral excision, was performed without complications. Histopathology confirmed a thyroglossal cyst. The six‑month follow‑up demonstrated complete healing and no recurrence. Early recognition and definitive transoral excision yield excellent outcomes while avoiding airway compromise.
