Zenker Diverticulum: A Potential Pitfall in Thyroid Ultrasound Evaluation: A Case Report and Systematic Review of Literature

Background and Objective: Zenker Diverticulum (ZD) can sometimes be misinterpreted as a thyroid nodule both at clinical evaluation and at Ultrasound (US). Case Presentation: We reported the case of a 46-years-old woman complaining of a lump in the anterior left aspect of the neck. Following clinical examination and US evaluation, a thyroid nodule was initially diagnosed and the patient was referred to our institution to be submitted to a fine-needle aspiration cytology. Management and Outcome: A ZD was suspected by US and diagnosed by gastrografin esophagram, thus an endoscopic diverticulotomy was requested. Conclusion: A correct US evaluation can be crucial for the appropriate management of a neck mass.
