Purpose
Zenker’s diverticulum (ZD) incidentally detected on neck ultrasound (US) could be easily misdiagnosed as a thyroid nodule and unnecessarily removed by surgical operation. It is a critical issue to identify the characteristics of ZD in clinical practice.
Methods
We reported 10 cases of ZD diagnosed using multimodal US, and discussed the features of its multimodal US images extracted from grayscale sonograms, color Doppler flow imaging (CDFI), three-dimensional US (3D-US), and contrast-enhanced US (CEUS).
Results
All lesions were heterogeneous in the posterior of the left thyroid. CDFI showed no blood flow within the lesions. The shapes and internal echoes of the masses changed when patients swallowed or drank. Performing CEUS or 3D-US for those with atypical US findings was complementary to make the final diagnosis. Importantly, multimodal US helped to diagnose suspected small lesions in three cases in which the barium esophagram tests proved negative.
Conclusions
The US features of ZD detected by multiple modes of US can help in the collection of comprehensive imaging information on ZD, which should be used proactively to facilitate the correct diagnosis and to avoid misdiagnosis of ZD.
