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.
