Benign lesions that present as neck masses are relatively common findings in the pediatric otolaryngology practice. The differential diagnosis includes persistent fetal structures, such as thyroglossal duct and branchial cleft remnants, as well as vascular malformations, such as hemangiomas and arteriovenous malformations. Persistent fetal vascular structures, however, are less common. We describe a 2-year-old boy who presented with a mass in the anterior aspect of his neck that was determined to be a persistent anomalous fetal vein. We also discuss the embryology and development of the venous system in the neck, as well as the options for the diagnosis and management of benign vascular lesions that present as neck masses in the pediatric patient.
