Clinical presentations of pyriform sinus fistulas vary, and this sometimes leads to a delay in diagnosis and treatment. Recently, we experienced a case of recurrent cervical abscesses occurring after thyroidectomy in an adult affected by a bifidus pyriform sinus fistula. The diagnostic dilemma was related to the timing of events, with a single episode of acute suppurative thyroiditis having occurred 16 years before the onset of the more recent clinical scenario. An endoscopic approach allowed effective management of this clinical case.
