Cervical cystic vagal schwannoma mimicking a type 3 second branchial cleft cyst: a case report.

In this article, we report a rare case of a cervical cystic vagal schwannoma mimicking a type 3 second branchial cleft cyst clinically, radiologically and cytologically. Although schwannoma is rare, it should be considered in the differential diagnosis of cystic neck masses. This article suggests that Doppler ultrasonography, computed tomography and fine needle aspiration biopsy findings may not be sufficient to provide the correct preoperative diagnosis of cystic lateral neck masses and further imaging techniques may be required.
